Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494596, here are decompositions:

13 + 31494583 = 31494596
43 + 31494553 = 31494596
127 + 31494469 = 31494596
157 + 31494439 = 31494596
349 + 31494247 = 31494596
439 + 31494157 = 31494596
499 + 31494097 = 31494596
607 + 31493989 = 31494596

Showing the first eight; more decompositions exist.
