Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612744, here are decompositions:

5 + 31612739 = 31612744
11 + 31612733 = 31612744
17 + 31612727 = 31612744
83 + 31612661 = 31612744
197 + 31612547 = 31612744
257 + 31612487 = 31612744
263 + 31612481 = 31612744
353 + 31612391 = 31612744

Showing the first eight; more decompositions exist.
