Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584244, here are decompositions:

11 + 31584233 = 31584244
47 + 31584197 = 31584244
53 + 31584191 = 31584244
71 + 31584173 = 31584244
101 + 31584143 = 31584244
347 + 31583897 = 31584244
467 + 31583777 = 31584244
491 + 31583753 = 31584244

Showing the first eight; more decompositions exist.
