Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612080, here are decompositions:

11 + 31612069 = 31612080
37 + 31612043 = 31612080
67 + 31612013 = 31612080
83 + 31611997 = 31612080
139 + 31611941 = 31612080
163 + 31611917 = 31612080
173 + 31611907 = 31612080
197 + 31611883 = 31612080

Showing the first eight; more decompositions exist.
