[Tex/LaTex] Subject in a Beamer Presentation

beamertitles

I'm making a beamer presentation for a course, I want to include the name of the course in the title page but I don't know how to do it. I tried using \subject{Name of the Course} but it doesn't do anything, is this the right command?

\documentclass{beamer} 
\usetheme{Madrid} } \title [Small Title]{Long Title} 
\author[Person1 \and Person2]{Person1 \inst{1} \and Person2 \inst{2}} 
\institute[UNI]{\inst{1} UNI \and \inst{2} UNI} \subject{Advanced Microeconometrics} 
\date{The date} 
\subject{Name of the Course} 
\begin{document} 
\justifying 
\begin{frame} 
\titlepage 
\end{frame}

Taking from the comments and deleting one } you hat to much after \usetheme{Madrid}, adding the package ragged2e in order to use your command \justifying, and adding \end{document} to the end:

% arara: pdflatex 

\documentclass{beamer} 
\usepackage{ragged2e}
\usetheme{Madrid}
\title [Small Title]{Long Title} 
\author[Person1 \and Person2]{Person1 \inst{1} \and Person2 \inst{2}} 
\institute[UNI]{\inst{1} UNI \and \inst{2} UNI \\[3ex] {\large Advanced Microeconometrics}}
\date{The date} 
\subject{Name of the Course}

\begin{document} 
\justifying 
\begin{frame} 
\titlepage 
\end{frame} 
\end{document}
