Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617998, here are decompositions:

31 + 31617967 = 31617998
37 + 31617961 = 31617998
109 + 31617889 = 31617998
127 + 31617871 = 31617998
241 + 31617757 = 31617998
331 + 31617667 = 31617998
367 + 31617631 = 31617998
439 + 31617559 = 31617998

Showing the first eight; more decompositions exist.
