  Estimated friends:
  46137349^22             =  odd
  (2*46137349)^22        = couple
  (2*46137349+1)^22    =  odd
  Then:
  46137349^22+(2*46137349)^22-(2*46137349+1)^22 =  couple

Yes, that is an odd number, just like 17 ad 4711.  So what?  Your
expression does *not* give that result using the GMP demo.

  The result must be couple and negative.

We all agree with that (assuming couple = even), just as GMP does.
