You can use \substack:

If this is desired in inline math you can use \limits to obtain the limits underneath the summation symbol:

However this is not recommended as it may not look good depending on how much adjacent text there is as it will affect interline spacing.

Code:

\documentclass{article}
\usepackage{amsmath}
\begin{document}
\[
  \sum_{\substack{i=0 \\ i\neq 4}}^n i
\]

In inline math: $\sum_{\substack{i=0 \\ i\neq 4}}^n i$, or
$\sum\limits_{\substack{i=0 \\ i\neq 4}}^n i$
\end{document}
