Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6786, here are decompositions:

5 + 6781 = 6786
7 + 6779 = 6786
23 + 6763 = 6786
53 + 6733 = 6786
67 + 6719 = 6786
83 + 6703 = 6786
97 + 6689 = 6786
107 + 6679 = 6786

Showing the first eight; more decompositions exist.
