Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9720, here are decompositions:

23 + 9697 = 9720
31 + 9689 = 9720
41 + 9679 = 9720
43 + 9677 = 9720
59 + 9661 = 9720
71 + 9649 = 9720
89 + 9631 = 9720
97 + 9623 = 9720

Showing the first eight; more decompositions exist.
