Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12682, here are decompositions:

11 + 12671 = 12682
23 + 12659 = 12682
29 + 12653 = 12682
41 + 12641 = 12682
71 + 12611 = 12682
113 + 12569 = 12682
179 + 12503 = 12682
191 + 12491 = 12682

Showing the first eight; more decompositions exist.
