Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596638, here are decompositions:

67 + 31596571 = 31596638
97 + 31596541 = 31596638
127 + 31596511 = 31596638
331 + 31596307 = 31596638
487 + 31596151 = 31596638
571 + 31596067 = 31596638
631 + 31596007 = 31596638
709 + 31595929 = 31596638

Showing the first eight; more decompositions exist.
