Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466512, here are decompositions:

131 + 31466381 = 31466512
263 + 31466249 = 31466512
449 + 31466063 = 31466512
461 + 31466051 = 31466512
509 + 31466003 = 31466512
683 + 31465829 = 31466512
839 + 31465673 = 31466512
863 + 31465649 = 31466512

Showing the first eight; more decompositions exist.
