Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612090, here are decompositions:

11 + 31612079 = 31612090
47 + 31612043 = 31612090
149 + 31611941 = 31612090
173 + 31611917 = 31612090
179 + 31611911 = 31612090
197 + 31611893 = 31612090
239 + 31611851 = 31612090
353 + 31611737 = 31612090

Showing the first eight; more decompositions exist.
