Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468816, here are decompositions:

23 + 31468793 = 31468816
59 + 31468757 = 31468816
89 + 31468727 = 31468816
149 + 31468667 = 31468816
179 + 31468637 = 31468816
227 + 31468589 = 31468816
257 + 31468559 = 31468816
263 + 31468553 = 31468816

Showing the first eight; more decompositions exist.
