Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496646, here are decompositions:

47 + 31496599 = 31496646
53 + 31496593 = 31496646
59 + 31496587 = 31496646
73 + 31496573 = 31496646
79 + 31496567 = 31496646
107 + 31496539 = 31496646
109 + 31496537 = 31496646
127 + 31496519 = 31496646

Showing the first eight; more decompositions exist.
