Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179280, here are decompositions:

11 + 179269 = 179280
19 + 179261 = 179280
37 + 179243 = 179280
47 + 179233 = 179280
67 + 179213 = 179280
71 + 179209 = 179280
107 + 179173 = 179280
113 + 179167 = 179280

Showing the first eight; more decompositions exist.
