Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612126, here are decompositions:

5 + 31612121 = 31612126
17 + 31612109 = 31612126
47 + 31612079 = 31612126
83 + 31612043 = 31612126
113 + 31612013 = 31612126
233 + 31611893 = 31612126
257 + 31611869 = 31612126
389 + 31611737 = 31612126

Showing the first eight; more decompositions exist.
