Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584, here are decompositions:

11 + 31573 = 31584
17 + 31567 = 31584
37 + 31547 = 31584
41 + 31543 = 31584
43 + 31541 = 31584
53 + 31531 = 31584
67 + 31517 = 31584
71 + 31513 = 31584

Showing the first eight; more decompositions exist.
