Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612164, here are decompositions:

13 + 31612151 = 31612164
43 + 31612121 = 31612164
83 + 31612081 = 31612164
151 + 31612013 = 31612164
167 + 31611997 = 31612164
223 + 31611941 = 31612164
257 + 31611907 = 31612164
271 + 31611893 = 31612164

Showing the first eight; more decompositions exist.
