Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612348, here are decompositions:

41 + 31612307 = 31612348
71 + 31612277 = 31612348
107 + 31612241 = 31612348
149 + 31612199 = 31612348
197 + 31612151 = 31612348
227 + 31612121 = 31612348
239 + 31612109 = 31612348
269 + 31612079 = 31612348

Showing the first eight; more decompositions exist.
