Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10668, here are decompositions:

5 + 10663 = 10668
11 + 10657 = 10668
17 + 10651 = 10668
29 + 10639 = 10668
37 + 10631 = 10668
41 + 10627 = 10668
61 + 10607 = 10668
67 + 10601 = 10668

Showing the first eight; more decompositions exist.
