Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612686, here are decompositions:

19 + 31612667 = 31612686
23 + 31612663 = 31612686
59 + 31612627 = 31612686
67 + 31612619 = 31612686
89 + 31612597 = 31612686
97 + 31612589 = 31612686
103 + 31612583 = 31612686
113 + 31612573 = 31612686

Showing the first eight; more decompositions exist.
