Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584164, here are decompositions:

97 + 31584067 = 31584164
181 + 31583983 = 31584164
193 + 31583971 = 31584164
223 + 31583941 = 31584164
307 + 31583857 = 31584164
463 + 31583701 = 31584164
523 + 31583641 = 31584164
643 + 31583521 = 31584164

Showing the first eight; more decompositions exist.
