Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584250, here are decompositions:

3 + 31584247 = 31584250
17 + 31584233 = 31584250
53 + 31584197 = 31584250
59 + 31584191 = 31584250
107 + 31584143 = 31584250
149 + 31584101 = 31584250
251 + 31583999 = 31584250
353 + 31583897 = 31584250

Showing the first eight; more decompositions exist.
