Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467646, here are decompositions:

53 + 31467593 = 31467646
59 + 31467587 = 31467646
107 + 31467539 = 31467646
113 + 31467533 = 31467646
137 + 31467509 = 31467646
149 + 31467497 = 31467646
179 + 31467467 = 31467646
227 + 31467419 = 31467646

Showing the first eight; more decompositions exist.
