Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9816, here are decompositions:

5 + 9811 = 9816
13 + 9803 = 9816
29 + 9787 = 9816
47 + 9769 = 9816
67 + 9749 = 9816
73 + 9743 = 9816
83 + 9733 = 9816
97 + 9719 = 9816

Showing the first eight; more decompositions exist.
