Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624794, here are decompositions:

11 + 31624783 = 31624794
13 + 31624781 = 31624794
31 + 31624763 = 31624794
41 + 31624753 = 31624794
53 + 31624741 = 31624794
151 + 31624643 = 31624794
163 + 31624631 = 31624794
167 + 31624627 = 31624794

Showing the first eight; more decompositions exist.
