Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9730, here are decompositions:

11 + 9719 = 9730
41 + 9689 = 9730
53 + 9677 = 9730
101 + 9629 = 9730
107 + 9623 = 9730
179 + 9551 = 9730
191 + 9539 = 9730
197 + 9533 = 9730

Showing the first eight; more decompositions exist.
