Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167158, here are decompositions:

41 + 167117 = 167158
59 + 167099 = 167158
71 + 167087 = 167158
107 + 167051 = 167158
137 + 167021 = 167158
149 + 167009 = 167158
179 + 166979 = 167158
191 + 166967 = 167158

Showing the first eight; more decompositions exist.
