Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6660, here are decompositions:

7 + 6653 = 6660
23 + 6637 = 6660
41 + 6619 = 6660
53 + 6607 = 6660
61 + 6599 = 6660
79 + 6581 = 6660
83 + 6577 = 6660
89 + 6571 = 6660

Showing the first eight; more decompositions exist.
