Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496756, here are decompositions:

37 + 31496719 = 31496756
79 + 31496677 = 31496756
157 + 31496599 = 31496756
163 + 31496593 = 31496756
307 + 31496449 = 31496756
337 + 31496419 = 31496756
367 + 31496389 = 31496756
439 + 31496317 = 31496756

Showing the first eight; more decompositions exist.
