Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584194, here are decompositions:

3 + 31584191 = 31584194
127 + 31584067 = 31584194
151 + 31584043 = 31584194
211 + 31583983 = 31584194
223 + 31583971 = 31584194
283 + 31583911 = 31584194
331 + 31583863 = 31584194
337 + 31583857 = 31584194

Showing the first eight; more decompositions exist.
