Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468966, here are decompositions:

3 + 31468963 = 31468966
47 + 31468919 = 31468966
173 + 31468793 = 31468966
239 + 31468727 = 31468966
443 + 31468523 = 31468966
449 + 31468517 = 31468966
467 + 31468499 = 31468966
563 + 31468403 = 31468966

Showing the first eight; more decompositions exist.
