Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584516, here are decompositions:

17 + 31584499 = 31584516
59 + 31584457 = 31584516
109 + 31584407 = 31584516
127 + 31584389 = 31584516
179 + 31584337 = 31584516
193 + 31584323 = 31584516
269 + 31584247 = 31584516
283 + 31584233 = 31584516

Showing the first eight; more decompositions exist.
