Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6730, here are decompositions:

11 + 6719 = 6730
29 + 6701 = 6730
41 + 6689 = 6730
71 + 6659 = 6730
131 + 6599 = 6730
149 + 6581 = 6730
167 + 6563 = 6730
179 + 6551 = 6730

Showing the first eight; more decompositions exist.
