Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467682, here are decompositions:

5 + 31467677 = 31467682
89 + 31467593 = 31467682
131 + 31467551 = 31467682
149 + 31467533 = 31467682
173 + 31467509 = 31467682
179 + 31467503 = 31467682
251 + 31467431 = 31467682
263 + 31467419 = 31467682

Showing the first eight; more decompositions exist.
