Indent wrapped chapter title

Question

I want to indent the title block of my chapter heading. The code below is almost exactly how I want chapter titles displayed except for the fact that the second line and onward of the chapter title are aligned with the chapter number. How do I do this?

\documentclass{report}
\usepackage{titlesec}    
\titleformat{\chapter}[display]
{\normalfont\Huge\bfseries}{\chaptertitlename\ \thechapter}{20pt}{\Large \thechapter\ \quad}

\begin{document}
    \tableofcontents
\chapter{Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction }
\section{Motivation}
\end{document}

What I want

Leandriis comment is related. However I did it a different way after someone suggested using minipages:

\documentclass{report}
\usepackage{titlesec}    
\titleformat{\chapter}[display]
{\normalfont\Huge\bfseries}{\chaptertitlename\ \thechapter}{20pt}{\Large \thechapter\ \quad}

\titleformat{\chapter}[display]
{\bfseries\huge}% note that \bfseries has no effect with the default fonts
{\filright\chaptertitlename~\thechapter}
{0ex}
{\vspace{1ex}%
    \Large \begin{minipage}[t]{0.05\textwidth}\thechapter\end{minipage} \hspace{0.05\linewidth} \begin{minipage}[t]{.9\textwidth}}
    [\end{minipage}]

\begin{document}
    \tableofcontents
\chapter{Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction }
\section{Motivation}
\end{document}

It's simple with the linegoal package:

\documentclass{report}
\usepackage{titlesec}
\usepackage{linegoal}
\titleformat{\chapter}[display]
{\normalfont\Huge\bfseries}{\chaptertitlename\ \thechapter}{20pt}{\Large \thechapter\ \quad\parbox[t]{\linegoal}}

\begin{document}

    \tableofcontents

\chapter{Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction Introduction }
\section{Motivation}

\end{document}
