Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584084, here are decompositions:

17 + 31584067 = 31584084
41 + 31584043 = 31584084
101 + 31583983 = 31584084
113 + 31583971 = 31584084
163 + 31583921 = 31584084
173 + 31583911 = 31584084
227 + 31583857 = 31584084
281 + 31583803 = 31584084

Showing the first eight; more decompositions exist.
