Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493054, here are decompositions:

7 + 31493047 = 31493054
37 + 31493017 = 31493054
277 + 31492777 = 31493054
283 + 31492771 = 31493054
457 + 31492597 = 31493054
487 + 31492567 = 31493054
577 + 31492477 = 31493054
601 + 31492453 = 31493054

Showing the first eight; more decompositions exist.
