Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9664, here are decompositions:

3 + 9661 = 9664
41 + 9623 = 9664
113 + 9551 = 9664
131 + 9533 = 9664
167 + 9497 = 9664
173 + 9491 = 9664
191 + 9473 = 9664
197 + 9467 = 9664

Showing the first eight; more decompositions exist.
