Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612134, here are decompositions:

13 + 31612121 = 31612134
53 + 31612081 = 31612134
137 + 31611997 = 31612134
193 + 31611941 = 31612134
223 + 31611911 = 31612134
227 + 31611907 = 31612134
241 + 31611893 = 31612134
251 + 31611883 = 31612134

Showing the first eight; more decompositions exist.
