Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584796, here are decompositions:

83 + 31584713 = 31584796
107 + 31584689 = 31584796
179 + 31584617 = 31584796
389 + 31584407 = 31584796
563 + 31584233 = 31584796
599 + 31584197 = 31584796
653 + 31584143 = 31584796
797 + 31583999 = 31584796

Showing the first eight; more decompositions exist.
