Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507834, here are decompositions:

11 + 31507823 = 31507834
41 + 31507793 = 31507834
47 + 31507787 = 31507834
131 + 31507703 = 31507834
167 + 31507667 = 31507834
173 + 31507661 = 31507834
227 + 31507607 = 31507834
251 + 31507583 = 31507834

Showing the first eight; more decompositions exist.
