Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12584, here are decompositions:

7 + 12577 = 12584
31 + 12553 = 12584
37 + 12547 = 12584
43 + 12541 = 12584
67 + 12517 = 12584
73 + 12511 = 12584
97 + 12487 = 12584
127 + 12457 = 12584

Showing the first eight; more decompositions exist.
