Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612046, here are decompositions:

3 + 31612043 = 31612046
139 + 31611907 = 31612046
163 + 31611883 = 31612046
229 + 31611817 = 31612046
313 + 31611733 = 31612046
337 + 31611709 = 31612046
373 + 31611673 = 31612046
379 + 31611667 = 31612046

Showing the first eight; more decompositions exist.
