Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9732, here are decompositions:

11 + 9721 = 9732
13 + 9719 = 9732
43 + 9689 = 9732
53 + 9679 = 9732
71 + 9661 = 9732
83 + 9649 = 9732
89 + 9643 = 9732
101 + 9631 = 9732

Showing the first eight; more decompositions exist.
