Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467658, here are decompositions:

11 + 31467647 = 31467658
71 + 31467587 = 31467658
107 + 31467551 = 31467658
149 + 31467509 = 31467658
191 + 31467467 = 31467658
227 + 31467431 = 31467658
239 + 31467419 = 31467658
269 + 31467389 = 31467658

Showing the first eight; more decompositions exist.
