Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612702, here are decompositions:

41 + 31612661 = 31612702
83 + 31612619 = 31612702
113 + 31612589 = 31612702
311 + 31612391 = 31612702
389 + 31612313 = 31612702
461 + 31612241 = 31612702
479 + 31612223 = 31612702
503 + 31612199 = 31612702

Showing the first eight; more decompositions exist.
