Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179428, here are decompositions:

17 + 179411 = 179428
47 + 179381 = 179428
59 + 179369 = 179428
71 + 179357 = 179428
101 + 179327 = 179428
107 + 179321 = 179428
167 + 179261 = 179428
317 + 179111 = 179428

Showing the first eight; more decompositions exist.
