Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9728, here are decompositions:

7 + 9721 = 9728
31 + 9697 = 9728
67 + 9661 = 9728
79 + 9649 = 9728
97 + 9631 = 9728
109 + 9619 = 9728
127 + 9601 = 9728
181 + 9547 = 9728

Showing the first eight; more decompositions exist.
