Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612084, here are decompositions:

3 + 31612081 = 31612084
5 + 31612079 = 31612084
41 + 31612043 = 31612084
71 + 31612013 = 31612084
167 + 31611917 = 31612084
173 + 31611911 = 31612084
191 + 31611893 = 31612084
233 + 31611851 = 31612084

Showing the first eight; more decompositions exist.
