Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596688, here are decompositions:

17 + 31596671 = 31596688
191 + 31596497 = 31596688
251 + 31596437 = 31596688
269 + 31596419 = 31596688
479 + 31596209 = 31596688
569 + 31596119 = 31596688
647 + 31596041 = 31596688
659 + 31596029 = 31596688

Showing the first eight; more decompositions exist.
