Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612146, here are decompositions:

37 + 31612109 = 31612146
67 + 31612079 = 31612146
103 + 31612043 = 31612146
149 + 31611997 = 31612146
229 + 31611917 = 31612146
239 + 31611907 = 31612146
263 + 31611883 = 31612146
277 + 31611869 = 31612146

Showing the first eight; more decompositions exist.
