Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492576, here are decompositions:

23 + 31492553 = 31492576
47 + 31492529 = 31492576
83 + 31492493 = 31492576
173 + 31492403 = 31492576
239 + 31492337 = 31492576
257 + 31492319 = 31492576
317 + 31492259 = 31492576
419 + 31492157 = 31492576

Showing the first eight; more decompositions exist.
