Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613224, here are decompositions:

53 + 31613171 = 31613224
107 + 31613117 = 31613224
197 + 31613027 = 31613224
233 + 31612991 = 31613224
263 + 31612961 = 31613224
311 + 31612913 = 31613224
491 + 31612733 = 31613224
557 + 31612667 = 31613224

Showing the first eight; more decompositions exist.
