Talk:Integer as Sum of Two Squares

I would like to add a proof for the last half part of the sufficient condition, using First Supplement to Law of Quadratic Reciprocity. But I think I will make the page messy if I add it directly... Z423x5c6 (talk) 11:37, 13 October 2017 (EDT)

Maybe we can move the different proofs to something like Prime Divisors of Sum of Coprime Squares Modulo 4? --barto (talk) 13:19, 13 October 2017 (EDT)

That sounds like the best approach. --prime mover (talk) 04:23, 14 October 2017 (EDT)
