Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6678, here are decompositions:

5 + 6673 = 6678
17 + 6661 = 6678
19 + 6659 = 6678
41 + 6637 = 6678
59 + 6619 = 6678
71 + 6607 = 6678
79 + 6599 = 6678
97 + 6581 = 6678

Showing the first eight; more decompositions exist.
