Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612936, here are decompositions:

23 + 31612913 = 31612936
83 + 31612853 = 31612936
197 + 31612739 = 31612936
269 + 31612667 = 31612936
317 + 31612619 = 31612936
347 + 31612589 = 31612936
353 + 31612583 = 31612936
389 + 31612547 = 31612936

Showing the first eight; more decompositions exist.
