Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612266, here are decompositions:

43 + 31612223 = 31612266
67 + 31612199 = 31612266
157 + 31612109 = 31612266
197 + 31612069 = 31612266
223 + 31612043 = 31612266
269 + 31611997 = 31612266
349 + 31611917 = 31612266
359 + 31611907 = 31612266

Showing the first eight; more decompositions exist.
