Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584254, here are decompositions:

7 + 31584247 = 31584254
43 + 31584211 = 31584254
61 + 31584193 = 31584254
211 + 31584043 = 31584254
271 + 31583983 = 31584254
283 + 31583971 = 31584254
313 + 31583941 = 31584254
397 + 31583857 = 31584254

Showing the first eight; more decompositions exist.
