Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612666, here are decompositions:

3 + 31612663 = 31612666
5 + 31612661 = 31612666
47 + 31612619 = 31612666
83 + 31612583 = 31612666
179 + 31612487 = 31612666
353 + 31612313 = 31612666
359 + 31612307 = 31612666
389 + 31612277 = 31612666

Showing the first eight; more decompositions exist.
