Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567968, here are decompositions:

7 + 31567961 = 31567968
37 + 31567931 = 31567968
109 + 31567859 = 31567968
149 + 31567819 = 31567968
199 + 31567769 = 31567968
227 + 31567741 = 31567968
239 + 31567729 = 31567968
251 + 31567717 = 31567968

Showing the first eight; more decompositions exist.
