Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9680, here are decompositions:

3 + 9677 = 9680
19 + 9661 = 9680
31 + 9649 = 9680
37 + 9643 = 9680
61 + 9619 = 9680
67 + 9613 = 9680
79 + 9601 = 9680
241 + 9439 = 9680

Showing the first eight; more decompositions exist.
