Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612068, here are decompositions:

71 + 31611997 = 31612068
127 + 31611941 = 31612068
151 + 31611917 = 31612068
157 + 31611911 = 31612068
199 + 31611869 = 31612068
227 + 31611841 = 31612068
239 + 31611829 = 31612068
251 + 31611817 = 31612068

Showing the first eight; more decompositions exist.
