Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179728, here are decompositions:

11 + 179717 = 179728
41 + 179687 = 179728
71 + 179657 = 179728
137 + 179591 = 179728
149 + 179579 = 179728
179 + 179549 = 179728
257 + 179471 = 179728
317 + 179411 = 179728

Showing the first eight; more decompositions exist.
