Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467736, here are decompositions:

17 + 31467719 = 31467736
59 + 31467677 = 31467736
89 + 31467647 = 31467736
149 + 31467587 = 31467736
197 + 31467539 = 31467736
227 + 31467509 = 31467736
233 + 31467503 = 31467736
239 + 31467497 = 31467736

Showing the first eight; more decompositions exist.
