Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467766, here are decompositions:

3 + 31467763 = 31467766
47 + 31467719 = 31467766
89 + 31467677 = 31467766
173 + 31467593 = 31467766
179 + 31467587 = 31467766
227 + 31467539 = 31467766
233 + 31467533 = 31467766
257 + 31467509 = 31467766

Showing the first eight; more decompositions exist.
