Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612066, here are decompositions:

23 + 31612043 = 31612066
53 + 31612013 = 31612066
149 + 31611917 = 31612066
173 + 31611893 = 31612066
197 + 31611869 = 31612066
263 + 31611803 = 31612066
347 + 31611719 = 31612066
419 + 31611647 = 31612066

Showing the first eight; more decompositions exist.
