Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584248, here are decompositions:

37 + 31584211 = 31584248
109 + 31584139 = 31584248
181 + 31584067 = 31584248
229 + 31584019 = 31584248
277 + 31583971 = 31584248
307 + 31583941 = 31584248
337 + 31583911 = 31584248
439 + 31583809 = 31584248

Showing the first eight; more decompositions exist.
