Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463758, here are decompositions:

41 + 31463717 = 31463758
167 + 31463591 = 31463758
239 + 31463519 = 31463758
251 + 31463507 = 31463758
269 + 31463489 = 31463758
281 + 31463477 = 31463758
509 + 31463249 = 31463758
659 + 31463099 = 31463758

Showing the first eight; more decompositions exist.
