Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584134, here are decompositions:

67 + 31584067 = 31584134
151 + 31583983 = 31584134
163 + 31583971 = 31584134
193 + 31583941 = 31584134
223 + 31583911 = 31584134
271 + 31583863 = 31584134
277 + 31583857 = 31584134
331 + 31583803 = 31584134

Showing the first eight; more decompositions exist.
