Find all problems that equal an integer
Let's give VIM some love (96 chars)

let n=input('')|for x in range(1,n/2-1)|for y in range(1,n)|if x*y==n|ec x."*".y|en|endfo|endfo


The abbreviations ec, en and endfo stand for echo, endif and endfor respectively.

I was rather disappointed that I couldn't use fo; that expands to fold.
