Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6668, here are decompositions:

7 + 6661 = 6668
31 + 6637 = 6668
61 + 6607 = 6668
97 + 6571 = 6668
139 + 6529 = 6668
199 + 6469 = 6668
241 + 6427 = 6668
271 + 6397 = 6668

Showing the first eight; more decompositions exist.
