Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9642, here are decompositions:

11 + 9631 = 9642
13 + 9629 = 9642
19 + 9623 = 9642
23 + 9619 = 9642
29 + 9613 = 9642
41 + 9601 = 9642
103 + 9539 = 9642
109 + 9533 = 9642

Showing the first eight; more decompositions exist.
