Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12564, here are decompositions:

11 + 12553 = 12564
17 + 12547 = 12564
23 + 12541 = 12564
37 + 12527 = 12564
47 + 12517 = 12564
53 + 12511 = 12564
61 + 12503 = 12564
67 + 12497 = 12564

Showing the first eight; more decompositions exist.
