Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507602, here are decompositions:

11 + 31507591 = 31507602
19 + 31507583 = 31507602
29 + 31507573 = 31507602
31 + 31507571 = 31507602
41 + 31507561 = 31507602
79 + 31507523 = 31507602
199 + 31507403 = 31507602
239 + 31507363 = 31507602

Showing the first eight; more decompositions exist.
