Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616956, here are decompositions:

5 + 31616951 = 31616956
23 + 31616933 = 31616956
53 + 31616903 = 31616956
227 + 31616729 = 31616956
263 + 31616693 = 31616956
269 + 31616687 = 31616956
353 + 31616603 = 31616956
563 + 31616393 = 31616956

Showing the first eight; more decompositions exist.
