Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167188, here are decompositions:

11 + 167177 = 167188
29 + 167159 = 167188
71 + 167117 = 167188
89 + 167099 = 167188
101 + 167087 = 167188
107 + 167081 = 167188
137 + 167051 = 167188
149 + 167039 = 167188

Showing the first eight; more decompositions exist.
