Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492762, here are decompositions:

5 + 31492757 = 31492762
11 + 31492751 = 31492762
71 + 31492691 = 31492762
233 + 31492529 = 31492762
269 + 31492493 = 31492762
359 + 31492403 = 31492762
443 + 31492319 = 31492762
503 + 31492259 = 31492762

Showing the first eight; more decompositions exist.
