Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612306, here are decompositions:

29 + 31612277 = 31612306
83 + 31612223 = 31612306
107 + 31612199 = 31612306
197 + 31612109 = 31612306
227 + 31612079 = 31612306
263 + 31612043 = 31612306
293 + 31612013 = 31612306
389 + 31611917 = 31612306

Showing the first eight; more decompositions exist.
