Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68672, here are decompositions:

3 + 68669 = 68672
13 + 68659 = 68672
61 + 68611 = 68672
151 + 68521 = 68672
181 + 68491 = 68672
199 + 68473 = 68672
223 + 68449 = 68672
229 + 68443 = 68672

Showing the first eight; more decompositions exist.
