Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9724, here are decompositions:

3 + 9721 = 9724
5 + 9719 = 9724
47 + 9677 = 9724
101 + 9623 = 9724
137 + 9587 = 9724
173 + 9551 = 9724
191 + 9533 = 9724
227 + 9497 = 9724

Showing the first eight; more decompositions exist.
