Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492826, here are decompositions:

163 + 31492663 = 31492826
199 + 31492627 = 31492826
223 + 31492603 = 31492826
229 + 31492597 = 31492826
349 + 31492477 = 31492826
373 + 31492453 = 31492826
397 + 31492429 = 31492826
433 + 31492393 = 31492826

Showing the first eight; more decompositions exist.
