Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492756, here are decompositions:

5 + 31492751 = 31492756
59 + 31492697 = 31492756
89 + 31492667 = 31492756
179 + 31492577 = 31492756
227 + 31492529 = 31492756
263 + 31492493 = 31492756
353 + 31492403 = 31492756
419 + 31492337 = 31492756

Showing the first eight; more decompositions exist.
