Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467708, here are decompositions:

17 + 31467691 = 31467708
31 + 31467677 = 31467708
61 + 31467647 = 31467708
137 + 31467571 = 31467708
149 + 31467559 = 31467708
157 + 31467551 = 31467708
199 + 31467509 = 31467708
211 + 31467497 = 31467708

Showing the first eight; more decompositions exist.
