Sorry before I tell you the question here was the question that led to this question.

Show that (m^2+1)(n^2+1)=(m+n)^2+(mn-1)^2

Done that successfully.

Using this results, write 500050 as the sum of 2 square numbers.

I have no idea how to make a knowledgeable guess at the two squares so I've tried using random (well, not exactly, generic random numbers) to get an answer but to no avail
