Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13668, here are decompositions:

19 + 13649 = 13668
41 + 13627 = 13668
71 + 13597 = 13668
101 + 13567 = 13668
131 + 13537 = 13668
181 + 13487 = 13668
191 + 13477 = 13668
199 + 13469 = 13668

Showing the first eight; more decompositions exist.
