Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166954, here are decompositions:

5 + 166949 = 166954
23 + 166931 = 166954
83 + 166871 = 166954
101 + 166853 = 166954
107 + 166847 = 166954
113 + 166841 = 166954
131 + 166823 = 166954
173 + 166781 = 166954

Showing the first eight; more decompositions exist.
