Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17668, here are decompositions:

11 + 17657 = 17668
41 + 17627 = 17668
59 + 17609 = 17668
71 + 17597 = 17668
89 + 17579 = 17668
149 + 17519 = 17668
179 + 17489 = 17668
191 + 17477 = 17668

Showing the first eight; more decompositions exist.
