Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492676, here are decompositions:

13 + 31492663 = 31492676
73 + 31492603 = 31492676
79 + 31492597 = 31492676
109 + 31492567 = 31492676
139 + 31492537 = 31492676
199 + 31492477 = 31492676
223 + 31492453 = 31492676
277 + 31492399 = 31492676

Showing the first eight; more decompositions exist.
