Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611656, here are decompositions:

73 + 31611583 = 31611656
79 + 31611577 = 31611656
103 + 31611553 = 31611656
199 + 31611457 = 31611656
277 + 31611379 = 31611656
337 + 31611319 = 31611656
607 + 31611049 = 31611656
613 + 31611043 = 31611656

Showing the first eight; more decompositions exist.
