Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22680, here are decompositions:

11 + 22669 = 22680
29 + 22651 = 22680
37 + 22643 = 22680
41 + 22639 = 22680
43 + 22637 = 22680
59 + 22621 = 22680
61 + 22619 = 22680
67 + 22613 = 22680

Showing the first eight; more decompositions exist.
