Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492634, here are decompositions:

7 + 31492627 = 31492634
31 + 31492603 = 31492634
37 + 31492597 = 31492634
67 + 31492567 = 31492634
97 + 31492537 = 31492634
157 + 31492477 = 31492634
163 + 31492471 = 31492634
181 + 31492453 = 31492634

Showing the first eight; more decompositions exist.
