Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167170, here are decompositions:

11 + 167159 = 167170
53 + 167117 = 167170
71 + 167099 = 167170
83 + 167087 = 167170
89 + 167081 = 167170
131 + 167039 = 167170
137 + 167033 = 167170
149 + 167021 = 167170

Showing the first eight; more decompositions exist.
