Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596368, here are decompositions:

61 + 31596307 = 31596368
241 + 31596127 = 31596368
379 + 31595989 = 31596368
439 + 31595929 = 31596368
487 + 31595881 = 31596368
499 + 31595869 = 31596368
757 + 31595611 = 31596368
787 + 31595581 = 31596368

Showing the first eight; more decompositions exist.
