Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584038, here are decompositions:

19 + 31584019 = 31584038
67 + 31583971 = 31584038
97 + 31583941 = 31584038
127 + 31583911 = 31584038
181 + 31583857 = 31584038
229 + 31583809 = 31584038
337 + 31583701 = 31584038
379 + 31583659 = 31584038

Showing the first eight; more decompositions exist.
