Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584096, here are decompositions:

29 + 31584067 = 31584096
53 + 31584043 = 31584096
97 + 31583999 = 31584096
107 + 31583989 = 31584096
113 + 31583983 = 31584096
199 + 31583897 = 31584096
233 + 31583863 = 31584096
239 + 31583857 = 31584096

Showing the first eight; more decompositions exist.
