Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9666, here are decompositions:

5 + 9661 = 9666
17 + 9649 = 9666
23 + 9643 = 9666
37 + 9629 = 9666
43 + 9623 = 9666
47 + 9619 = 9666
53 + 9613 = 9666
79 + 9587 = 9666

Showing the first eight; more decompositions exist.
