Change style of chapter headings in report class document

Question

I'm using that kind of page numbering:

\documentclass[12pt,a4paper,twoside]{report}
\begin{document}
\part{Part name}
...
\chapter{Chapter name}
...
\section{Section name}
...
\subsection{Subsection name}
\end{document}

In chapter section it gives this result:

But I would like to achieve different chapter formatting, like this:

Is this is possible without changing the report class of the document?

\chapter{Chapter name}
...
\section{Section name}
...
\subsection{Subsection name}
\end{document}
