Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179638, here are decompositions:

5 + 179633 = 179638
47 + 179591 = 179638
59 + 179579 = 179638
89 + 179549 = 179638
167 + 179471 = 179638
197 + 179441 = 179638
227 + 179411 = 179638
257 + 179381 = 179638

Showing the first eight; more decompositions exist.
