Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166972, here are decompositions:

5 + 166967 = 166972
23 + 166949 = 166972
41 + 166931 = 166972
53 + 166919 = 166972
101 + 166871 = 166972
131 + 166841 = 166972
149 + 166823 = 166972
173 + 166799 = 166972

Showing the first eight; more decompositions exist.
