Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6688, here are decompositions:

29 + 6659 = 6688
89 + 6599 = 6688
107 + 6581 = 6688
137 + 6551 = 6688
167 + 6521 = 6688
197 + 6491 = 6688
239 + 6449 = 6688
359 + 6329 = 6688

Showing the first eight; more decompositions exist.
