Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492754, here are decompositions:

3 + 31492751 = 31492754
103 + 31492651 = 31492754
127 + 31492627 = 31492754
151 + 31492603 = 31492754
157 + 31492597 = 31492754
277 + 31492477 = 31492754
283 + 31492471 = 31492754
331 + 31492423 = 31492754

Showing the first eight; more decompositions exist.
