Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6670, here are decompositions:

11 + 6659 = 6670
17 + 6653 = 6670
71 + 6599 = 6670
89 + 6581 = 6670
101 + 6569 = 6670
107 + 6563 = 6670
149 + 6521 = 6670
179 + 6491 = 6670

Showing the first eight; more decompositions exist.
