Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6800, here are decompositions:

7 + 6793 = 6800
19 + 6781 = 6800
37 + 6763 = 6800
67 + 6733 = 6800
97 + 6703 = 6800
109 + 6691 = 6800
127 + 6673 = 6800
139 + 6661 = 6800

Showing the first eight; more decompositions exist.
