Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167218, here are decompositions:

5 + 167213 = 167218
41 + 167177 = 167218
59 + 167159 = 167218
101 + 167117 = 167218
131 + 167087 = 167218
137 + 167081 = 167218
167 + 167051 = 167218
179 + 167039 = 167218

Showing the first eight; more decompositions exist.
