Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66808, here are decompositions:

11 + 66797 = 66808
17 + 66791 = 66808
59 + 66749 = 66808
107 + 66701 = 66808
179 + 66629 = 66808
191 + 66617 = 66808
239 + 66569 = 66808
317 + 66491 = 66808

Showing the first eight; more decompositions exist.
