Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553962, here are decompositions:

59 + 31553903 = 31553962
179 + 31553783 = 31553962
233 + 31553729 = 31553962
353 + 31553609 = 31553962
443 + 31553519 = 31553962
509 + 31553453 = 31553962
593 + 31553369 = 31553962
641 + 31553321 = 31553962

Showing the first eight; more decompositions exist.
