Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613006, here are decompositions:

37 + 31612969 = 31613006
67 + 31612939 = 31613006
277 + 31612729 = 31613006
379 + 31612627 = 31613006
409 + 31612597 = 31613006
433 + 31612573 = 31613006
577 + 31612429 = 31613006
643 + 31612363 = 31613006

Showing the first eight; more decompositions exist.
