Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612222, here are decompositions:

23 + 31612199 = 31612222
71 + 31612151 = 31612222
101 + 31612121 = 31612222
113 + 31612109 = 31612222
179 + 31612043 = 31612222
281 + 31611941 = 31612222
311 + 31611911 = 31612222
353 + 31611869 = 31612222

Showing the first eight; more decompositions exist.
