Of course they can be different (or must, as otherwise there's no such possibility). Is there a general formula that will help me evaluate all such prime numbers?
Can P0^2 = p1^2 + p2^2 + p3^2 + p4^2 + p5^2 Since all primes (except 2) are of the form: 2k+1 the lhs: 4k^2 + 4k + 1 After some additions and simplifications, the lhs & rhs will never have odd/even parity. Therefore to answer your question: NO.
