Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612974, here are decompositions:

5 + 31612969 = 31612974
13 + 31612961 = 31612974
23 + 31612951 = 31612974
61 + 31612913 = 31612974
83 + 31612891 = 31612974
101 + 31612873 = 31612974
227 + 31612747 = 31612974
241 + 31612733 = 31612974

Showing the first eight; more decompositions exist.
