Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584376, here are decompositions:

3 + 31584373 = 31584376
53 + 31584323 = 31584376
113 + 31584263 = 31584376
179 + 31584197 = 31584376
233 + 31584143 = 31584376
479 + 31583897 = 31584376
557 + 31583819 = 31584376
599 + 31583777 = 31584376

Showing the first eight; more decompositions exist.
