Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584624, here are decompositions:

7 + 31584617 = 31584624
11 + 31584613 = 31584624
17 + 31584607 = 31584624
23 + 31584601 = 31584624
47 + 31584577 = 31584624
73 + 31584551 = 31584624
83 + 31584541 = 31584624
101 + 31584523 = 31584624

Showing the first eight; more decompositions exist.
