Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167166, here are decompositions:

7 + 167159 = 167166
17 + 167149 = 167166
47 + 167119 = 167166
53 + 167113 = 167166
59 + 167107 = 167166
67 + 167099 = 167166
79 + 167087 = 167166
89 + 167077 = 167166

Showing the first eight; more decompositions exist.
