Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612074, here are decompositions:

5 + 31612069 = 31612074
31 + 31612043 = 31612074
61 + 31612013 = 31612074
157 + 31611917 = 31612074
163 + 31611911 = 31612074
167 + 31611907 = 31612074
181 + 31611893 = 31612074
191 + 31611883 = 31612074

Showing the first eight; more decompositions exist.
