Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10664, here are decompositions:

7 + 10657 = 10664
13 + 10651 = 10664
37 + 10627 = 10664
67 + 10597 = 10664
97 + 10567 = 10664
151 + 10513 = 10664
163 + 10501 = 10664
211 + 10453 = 10664

Showing the first eight; more decompositions exist.
