Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612308, here are decompositions:

31 + 31612277 = 31612308
67 + 31612241 = 31612308
107 + 31612201 = 31612308
109 + 31612199 = 31612308
157 + 31612151 = 31612308
199 + 31612109 = 31612308
227 + 31612081 = 31612308
229 + 31612079 = 31612308

Showing the first eight; more decompositions exist.
