Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6680, here are decompositions:

7 + 6673 = 6680
19 + 6661 = 6680
43 + 6637 = 6680
61 + 6619 = 6680
73 + 6607 = 6680
103 + 6577 = 6680
109 + 6571 = 6680
127 + 6553 = 6680

Showing the first eight; more decompositions exist.
