Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612088, here are decompositions:

7 + 31612081 = 31612088
19 + 31612069 = 31612088
181 + 31611907 = 31612088
271 + 31611817 = 31612088
331 + 31611757 = 31612088
379 + 31611709 = 31612088
421 + 31611667 = 31612088
601 + 31611487 = 31612088

Showing the first eight; more decompositions exist.
