Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612968, here are decompositions:

7 + 31612961 = 31612968
17 + 31612951 = 31612968
29 + 31612939 = 31612968
137 + 31612831 = 31612968
229 + 31612739 = 31612968
239 + 31612729 = 31612968
241 + 31612727 = 31612968
307 + 31612661 = 31612968

Showing the first eight; more decompositions exist.
