How can I exclude pages from this Boolean command?

Question

I was using the code from Harish Kumar's excellent answer to this question to create a link t my table of contents. However, I wanted to alter it so that the link did not appear on the first two pages.

I tried using the \everypage package to create a hook that would exclude the first two pages from the function, but I'm not sure how to nest the hook to fit with the \ifthenelse. Every attempt I tried to somehow combine in a hook, in various combinations, resulted in a compile error.

Here is the code, which, once again, I lifted from the earlier-linked excellent answer:

\documentclass{article}
\usepackage{blindtext}
\usepackage{eso-pic}
\usepackage{hyperref}
\usepackage{ifthen}
\newboolean{linktoc}
\setboolean{linktoc}{true}  %%% uncomment to show answers properly
%\setboolean{linktoc}{false}  %%% comment to show answers properly

\newcommand\AtPageUpperRight[1]{\AtPageUpperLeft{%
 \put(\LenToUnit{\paperwidth},\LenToUnit{-0.3\paperheight}){#1}%
 }}%
\newcommand\AtPageLowerRight[1]{\AtPageLowerLeft{%
 \put(\LenToUnit{\paperwidth},\LenToUnit{0.3\paperheight}){#1}%
 }}%

\ifthenelse{\boolean{linktoc}}%
{%
\AddToShipoutPictureBG{%
   \AtPageUpperRight{\put(-70,0){\hyperref[toc]{Go to TOC}}}
   \AtPageLowerRight{\put(-70,0){\hyperref[toc]{Go to TOC}}}
    }%
}%
{}%


\begin{document}
  \tableofcontents\label{toc}
  \Blinddocument
\end{document}

(I'm relatively new to using conditionals, so I apologize if my title or question uses incorrect terminology— please tell me if it does so I can edit it and make my question clearer)

You could condition on the value of the page counter, as you're adding content at the time of shipout (when the page counter is correct):

\documentclass{article}

\usepackage{blindtext}
\usepackage{eso-pic,hyperref}

\newif\iflinktoc
\linktoctrue%%% uncomment to show answers properly
%\linktocfalse%%% comment to show answers properly

\newcommand\AtPageUpperRight[1]{\AtPageUpperLeft{%
  \put(\LenToUnit{\paperwidth},\LenToUnit{-0.3\paperheight}){#1}%
}}%
\newcommand\AtPageLowerRight[1]{\AtPageLowerLeft{%
  \put(\LenToUnit{\paperwidth},\LenToUnit{0.3\paperheight}){#1}%
}}%

\newcommand{\addlinktotoc}{\hyperref[toc]{Go to ToC}}
\iflinktoc
  \AddToShipoutPictureBG{%
    \ifnum\value{page}<3\else
      \AtPageUpperRight{\put(-70,0){\addlinktotoc}}%
      \AtPageLowerRight{\put(-70,0){\addlinktotoc}}%
    \fi
  }%
\fi

\begin{document}

\tableofcontents\label{toc}
\Blinddocument

\end{document}

I've dropped the use of ifthen, based on Why is the ifthen package obsolete? and How to keep up with packages and know which ones are obsolete?.

Thank you! Good to know about ifthen — I had no idea it was obsolete — , Jan 03 '16 at 18:39
