Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68680, here are decompositions:

11 + 68669 = 68680
41 + 68639 = 68680
47 + 68633 = 68680
83 + 68597 = 68680
113 + 68567 = 68680
137 + 68543 = 68680
149 + 68531 = 68680
173 + 68507 = 68680

Showing the first eight; more decompositions exist.
