Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178118, here are decompositions:

79 + 178039 = 178118
97 + 178021 = 178118
139 + 177979 = 178118
151 + 177967 = 178118
211 + 177907 = 178118
229 + 177889 = 178118
277 + 177841 = 178118
307 + 177811 = 178118

Showing the first eight; more decompositions exist.
