Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612092, here are decompositions:

11 + 31612081 = 31612092
13 + 31612079 = 31612092
23 + 31612069 = 31612092
79 + 31612013 = 31612092
151 + 31611941 = 31612092
181 + 31611911 = 31612092
199 + 31611893 = 31612092
223 + 31611869 = 31612092

Showing the first eight; more decompositions exist.
