Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612708, here are decompositions:

41 + 31612667 = 31612708
47 + 31612661 = 31612708
89 + 31612619 = 31612708
227 + 31612481 = 31612708
317 + 31612391 = 31612708
401 + 31612307 = 31612708
431 + 31612277 = 31612708
467 + 31612241 = 31612708

Showing the first eight; more decompositions exist.
