Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6790, here are decompositions:

11 + 6779 = 6790
29 + 6761 = 6790
53 + 6737 = 6790
71 + 6719 = 6790
89 + 6701 = 6790
101 + 6689 = 6790
131 + 6659 = 6790
137 + 6653 = 6790

Showing the first eight; more decompositions exist.
