Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612612, here are decompositions:

23 + 31612589 = 31612612
29 + 31612583 = 31612612
131 + 31612481 = 31612612
389 + 31612223 = 31612612
461 + 31612151 = 31612612
491 + 31612121 = 31612612
503 + 31612109 = 31612612
569 + 31612043 = 31612612

Showing the first eight; more decompositions exist.
