Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612036, here are decompositions:

23 + 31612013 = 31612036
167 + 31611869 = 31612036
233 + 31611803 = 31612036
317 + 31611719 = 31612036
389 + 31611647 = 31612036
419 + 31611617 = 31612036
509 + 31611527 = 31612036
563 + 31611473 = 31612036

Showing the first eight; more decompositions exist.
