Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584006, here are decompositions:

7 + 31583999 = 31584006
17 + 31583989 = 31584006
23 + 31583983 = 31584006
109 + 31583897 = 31584006
149 + 31583857 = 31584006
197 + 31583809 = 31584006
227 + 31583779 = 31584006
229 + 31583777 = 31584006

Showing the first eight; more decompositions exist.
