Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612746, here are decompositions:

7 + 31612739 = 31612746
13 + 31612733 = 31612746
17 + 31612729 = 31612746
19 + 31612727 = 31612746
79 + 31612667 = 31612746
83 + 31612663 = 31612746
127 + 31612619 = 31612746
149 + 31612597 = 31612746

Showing the first eight; more decompositions exist.
