Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166996, here are decompositions:

17 + 166979 = 166996
23 + 166973 = 166996
29 + 166967 = 166996
47 + 166949 = 166996
149 + 166847 = 166996
173 + 166823 = 166996
197 + 166799 = 166996
257 + 166739 = 166996

Showing the first eight; more decompositions exist.
