Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12708, here are decompositions:

5 + 12703 = 12708
11 + 12697 = 12708
19 + 12689 = 12708
37 + 12671 = 12708
61 + 12647 = 12708
67 + 12641 = 12708
71 + 12637 = 12708
89 + 12619 = 12708

Showing the first eight; more decompositions exist.
