Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10680, here are decompositions:

13 + 10667 = 10680
17 + 10663 = 10680
23 + 10657 = 10680
29 + 10651 = 10680
41 + 10639 = 10680
53 + 10627 = 10680
67 + 10613 = 10680
73 + 10607 = 10680

Showing the first eight; more decompositions exist.
