Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613664, here are decompositions:

37 + 31613627 = 31613664
41 + 31613623 = 31613664
83 + 31613581 = 31613664
113 + 31613551 = 31613664
151 + 31613513 = 31613664
223 + 31613441 = 31613664
227 + 31613437 = 31613664
263 + 31613401 = 31613664

Showing the first eight; more decompositions exist.
