Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468810, here are decompositions:

17 + 31468793 = 31468810
53 + 31468757 = 31468810
83 + 31468727 = 31468810
173 + 31468637 = 31468810
179 + 31468631 = 31468810
239 + 31468571 = 31468810
251 + 31468559 = 31468810
257 + 31468553 = 31468810

Showing the first eight; more decompositions exist.
