\large \sum_{p^{m} \le x \atop \text{p is prime }m \ge 1 }

\(\displaystyle \large \sum_{p^{m} \le x \atop \text{p is prime }m \ge 1 } \)

The spacing and sizing could use a little work but it's a good start for now.

EDIT: Just found another one on the same page. Try this code as well:

\large \sum_{\substack{p^{m} \le x \\ \text{p is prime }m \ge 1}}

\(\displaystyle \large \sum_{\substack{p^{m} \le x \\ \text{p is prime }m \ge 1}}\)
