Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9636, here are decompositions:

5 + 9631 = 9636
7 + 9629 = 9636
13 + 9623 = 9636
17 + 9619 = 9636
23 + 9613 = 9636
89 + 9547 = 9636
97 + 9539 = 9636
103 + 9533 = 9636

Showing the first eight; more decompositions exist.
