Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166106, here are decompositions:

7 + 166099 = 166106
43 + 166063 = 166106
79 + 166027 = 166106
223 + 165883 = 166106
229 + 165877 = 166106
277 + 165829 = 166106
307 + 165799 = 166106
397 + 165709 = 166106

Showing the first eight; more decompositions exist.
