Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612016, here are decompositions:

3 + 31612013 = 31612016
19 + 31611997 = 31612016
109 + 31611907 = 31612016
199 + 31611817 = 31612016
283 + 31611733 = 31612016
307 + 31611709 = 31612016
313 + 31611703 = 31612016
349 + 31611667 = 31612016

Showing the first eight; more decompositions exist.
