Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584116, here are decompositions:

73 + 31584043 = 31584116
97 + 31584019 = 31584116
127 + 31583989 = 31584116
307 + 31583809 = 31584116
313 + 31583803 = 31584116
337 + 31583779 = 31584116
367 + 31583749 = 31584116
457 + 31583659 = 31584116

Showing the first eight; more decompositions exist.
