Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468804, here are decompositions:

11 + 31468793 = 31468804
47 + 31468757 = 31468804
137 + 31468667 = 31468804
167 + 31468637 = 31468804
173 + 31468631 = 31468804
233 + 31468571 = 31468804
251 + 31468553 = 31468804
281 + 31468523 = 31468804

Showing the first eight; more decompositions exist.
