Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584256, here are decompositions:

23 + 31584233 = 31584256
59 + 31584197 = 31584256
83 + 31584173 = 31584256
113 + 31584143 = 31584256
257 + 31583999 = 31584256
359 + 31583897 = 31584256
419 + 31583837 = 31584256
479 + 31583777 = 31584256

Showing the first eight; more decompositions exist.
