Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492604, here are decompositions:

7 + 31492597 = 31492604
37 + 31492567 = 31492604
67 + 31492537 = 31492604
127 + 31492477 = 31492604
151 + 31492453 = 31492604
181 + 31492423 = 31492604
211 + 31492393 = 31492604
523 + 31492081 = 31492604

Showing the first eight; more decompositions exist.
