Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584326, here are decompositions:

3 + 31584323 = 31584326
19 + 31584307 = 31584326
79 + 31584247 = 31584326
283 + 31584043 = 31584326
307 + 31584019 = 31584326
337 + 31583989 = 31584326
463 + 31583863 = 31584326
523 + 31583803 = 31584326

Showing the first eight; more decompositions exist.
