Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467666, here are decompositions:

19 + 31467647 = 31467666
73 + 31467593 = 31467666
79 + 31467587 = 31467666
107 + 31467559 = 31467666
127 + 31467539 = 31467666
157 + 31467509 = 31467666
163 + 31467503 = 31467666
199 + 31467467 = 31467666

Showing the first eight; more decompositions exist.
