Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617892, here are decompositions:

3 + 31617889 = 31617892
29 + 31617863 = 31617892
179 + 31617713 = 31617892
233 + 31617659 = 31617892
263 + 31617629 = 31617892
359 + 31617533 = 31617892
389 + 31617503 = 31617892
431 + 31617461 = 31617892

Showing the first eight; more decompositions exist.
