Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584264, here are decompositions:

17 + 31584247 = 31584264
31 + 31584233 = 31584264
53 + 31584211 = 31584264
67 + 31584197 = 31584264
71 + 31584193 = 31584264
73 + 31584191 = 31584264
163 + 31584101 = 31584264
197 + 31584067 = 31584264

Showing the first eight; more decompositions exist.
