Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612116, here are decompositions:

7 + 31612109 = 31612116
37 + 31612079 = 31612116
47 + 31612069 = 31612116
73 + 31612043 = 31612116
103 + 31612013 = 31612116
199 + 31611917 = 31612116
223 + 31611893 = 31612116
233 + 31611883 = 31612116

Showing the first eight; more decompositions exist.
