Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468834, here are decompositions:

11 + 31468823 = 31468834
41 + 31468793 = 31468834
107 + 31468727 = 31468834
167 + 31468667 = 31468834
197 + 31468637 = 31468834
263 + 31468571 = 31468834
281 + 31468553 = 31468834
311 + 31468523 = 31468834

Showing the first eight; more decompositions exist.
