Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612916, here are decompositions:

3 + 31612913 = 31612916
43 + 31612873 = 31612916
157 + 31612759 = 31612916
163 + 31612753 = 31612916
463 + 31612453 = 31612916
487 + 31612429 = 31612916
547 + 31612369 = 31612916
607 + 31612309 = 31612916

Showing the first eight; more decompositions exist.
