Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6728, here are decompositions:

19 + 6709 = 6728
37 + 6691 = 6728
67 + 6661 = 6728
109 + 6619 = 6728
151 + 6577 = 6728
157 + 6571 = 6728
181 + 6547 = 6728
199 + 6529 = 6728

Showing the first eight; more decompositions exist.
