Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9640, here are decompositions:

11 + 9629 = 9640
17 + 9623 = 9640
53 + 9587 = 9640
89 + 9551 = 9640
101 + 9539 = 9640
107 + 9533 = 9640
149 + 9491 = 9640
167 + 9473 = 9640

Showing the first eight; more decompositions exist.
