Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496156, here are decompositions:

37 + 31496119 = 31496156
73 + 31496083 = 31496156
277 + 31495879 = 31496156
337 + 31495819 = 31496156
463 + 31495693 = 31496156
499 + 31495657 = 31496156
709 + 31495447 = 31496156
733 + 31495423 = 31496156

Showing the first eight; more decompositions exist.
