Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611584, here are decompositions:

3 + 31611581 = 31611584
7 + 31611577 = 31611584
31 + 31611553 = 31611584
97 + 31611487 = 31611584
127 + 31611457 = 31611584
181 + 31611403 = 31611584
283 + 31611301 = 31611584
313 + 31611271 = 31611584

Showing the first eight; more decompositions exist.
