Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9756, here are decompositions:

7 + 9749 = 9756
13 + 9743 = 9756
17 + 9739 = 9756
23 + 9733 = 9756
37 + 9719 = 9756
59 + 9697 = 9756
67 + 9689 = 9756
79 + 9677 = 9756

Showing the first eight; more decompositions exist.
