Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584054, here are decompositions:

11 + 31584043 = 31584054
71 + 31583983 = 31584054
83 + 31583971 = 31584054
113 + 31583941 = 31584054
157 + 31583897 = 31584054
191 + 31583863 = 31584054
197 + 31583857 = 31584054
223 + 31583831 = 31584054

Showing the first eight; more decompositions exist.
