Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584206, here are decompositions:

13 + 31584193 = 31584206
67 + 31584139 = 31584206
139 + 31584067 = 31584206
163 + 31584043 = 31584206
223 + 31583983 = 31584206
349 + 31583857 = 31584206
397 + 31583809 = 31584206
457 + 31583749 = 31584206

Showing the first eight; more decompositions exist.
