Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12660, here are decompositions:

7 + 12653 = 12660
13 + 12647 = 12660
19 + 12641 = 12660
23 + 12637 = 12660
41 + 12619 = 12660
47 + 12613 = 12660
59 + 12601 = 12660
71 + 12589 = 12660

Showing the first eight; more decompositions exist.
