Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6630, here are decompositions:

11 + 6619 = 6630
23 + 6607 = 6630
31 + 6599 = 6630
53 + 6577 = 6630
59 + 6571 = 6630
61 + 6569 = 6630
67 + 6563 = 6630
79 + 6551 = 6630

Showing the first eight; more decompositions exist.
