Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584446, here are decompositions:

7 + 31584439 = 31584446
73 + 31584373 = 31584446
109 + 31584337 = 31584446
139 + 31584307 = 31584446
199 + 31584247 = 31584446
307 + 31584139 = 31584446
379 + 31584067 = 31584446
457 + 31583989 = 31584446

Showing the first eight; more decompositions exist.
