Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584110, here are decompositions:

43 + 31584067 = 31584110
67 + 31584043 = 31584110
127 + 31583983 = 31584110
139 + 31583971 = 31584110
199 + 31583911 = 31584110
307 + 31583803 = 31584110
331 + 31583779 = 31584110
409 + 31583701 = 31584110

Showing the first eight; more decompositions exist.
