Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179128, here are decompositions:

17 + 179111 = 179128
29 + 179099 = 179128
71 + 179057 = 179128
107 + 179021 = 179128
197 + 178931 = 179128
239 + 178889 = 179128
251 + 178877 = 179128
269 + 178859 = 179128

Showing the first eight; more decompositions exist.
