Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467760, here are decompositions:

41 + 31467719 = 31467760
83 + 31467677 = 31467760
113 + 31467647 = 31467760
167 + 31467593 = 31467760
173 + 31467587 = 31467760
227 + 31467533 = 31467760
251 + 31467509 = 31467760
257 + 31467503 = 31467760

Showing the first eight; more decompositions exist.
