pa2b2 small oddity

[Helge Gabert]

P=2 can be factored into (1+i)*(1-i), and can be written as a sum of squares, namely sq(1)+sq(1), so pa2b2 could be modified to allow for the solution of [1 1] if the user enters pa2b2(2). That's it.

So my suggestion is that pa2b2 would allow for arguments to include all primes congruent to 1 modulus 4, as well as the even prime 2.
