Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179158, here are decompositions:

47 + 179111 = 179158
59 + 179099 = 179158
101 + 179057 = 179158
107 + 179051 = 179158
137 + 179021 = 179158
227 + 178931 = 179158
251 + 178907 = 179158
269 + 178889 = 179158

Showing the first eight; more decompositions exist.
