Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68664, here are decompositions:

5 + 68659 = 68664
31 + 68633 = 68664
53 + 68611 = 68664
67 + 68597 = 68664
83 + 68581 = 68664
97 + 68567 = 68664
157 + 68507 = 68664
163 + 68501 = 68664

Showing the first eight; more decompositions exist.
