Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584008, here are decompositions:

19 + 31583989 = 31584008
37 + 31583971 = 31584008
67 + 31583941 = 31584008
97 + 31583911 = 31584008
151 + 31583857 = 31584008
199 + 31583809 = 31584008
229 + 31583779 = 31584008
307 + 31583701 = 31584008

Showing the first eight; more decompositions exist.
