Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612942, here are decompositions:

3 + 31612939 = 31612942
29 + 31612913 = 31612942
89 + 31612853 = 31612942
281 + 31612661 = 31612942
353 + 31612589 = 31612942
359 + 31612583 = 31612942
461 + 31612481 = 31612942
701 + 31612241 = 31612942

Showing the first eight; more decompositions exist.
