I have recently got some interest in Primes and tried to explore more and more in it. Late, at night 11:00, I found this beautiful theorem.

I found that" Every prime when divided by four gives a remainder 1 or -1.

Therefore, square of every prime leaves a remainder 1 when divided by 4.

(sum_{i=1}^n) P gives a remainder n when divided by 4.( where P is a prime)

The primes we take doesn't include 2.
