Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12668, here are decompositions:

31 + 12637 = 12668
67 + 12601 = 12668
79 + 12589 = 12668
127 + 12541 = 12668
151 + 12517 = 12668
157 + 12511 = 12668
181 + 12487 = 12668
211 + 12457 = 12668

Showing the first eight; more decompositions exist.
