Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611736, here are decompositions:

3 + 31611733 = 31611736
17 + 31611719 = 31611736
89 + 31611647 = 31611736
197 + 31611539 = 31611736
227 + 31611509 = 31611736
263 + 31611473 = 31611736
269 + 31611467 = 31611736
599 + 31611137 = 31611736

Showing the first eight; more decompositions exist.
