Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584356, here are decompositions:

19 + 31584337 = 31584356
109 + 31584247 = 31584356
163 + 31584193 = 31584356
313 + 31584043 = 31584356
337 + 31584019 = 31584356
367 + 31583989 = 31584356
373 + 31583983 = 31584356
499 + 31583857 = 31584356

Showing the first eight; more decompositions exist.
