Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584056, here are decompositions:

13 + 31584043 = 31584056
37 + 31584019 = 31584056
67 + 31583989 = 31584056
73 + 31583983 = 31584056
193 + 31583863 = 31584056
199 + 31583857 = 31584056
277 + 31583779 = 31584056
307 + 31583749 = 31584056

Showing the first eight; more decompositions exist.
