Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149166, here are decompositions:

5 + 149161 = 149166
7 + 149159 = 149166
13 + 149153 = 149166
23 + 149143 = 149166
47 + 149119 = 149166
53 + 149113 = 149166
67 + 149099 = 149166
79 + 149087 = 149166

Showing the first eight; more decompositions exist.
