Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179668, here are decompositions:

11 + 179657 = 179668
17 + 179651 = 179668
89 + 179579 = 179668
149 + 179519 = 179668
197 + 179471 = 179668
227 + 179441 = 179668
239 + 179429 = 179668
257 + 179411 = 179668

Showing the first eight; more decompositions exist.
