Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584086, here are decompositions:

19 + 31584067 = 31584086
43 + 31584043 = 31584086
67 + 31584019 = 31584086
97 + 31583989 = 31584086
103 + 31583983 = 31584086
223 + 31583863 = 31584086
229 + 31583857 = 31584086
277 + 31583809 = 31584086

Showing the first eight; more decompositions exist.
