Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166008, here are decompositions:

47 + 165961 = 166008
61 + 165947 = 166008
67 + 165941 = 166008
107 + 165901 = 166008
131 + 165877 = 166008
151 + 165857 = 166008
179 + 165829 = 166008
191 + 165817 = 166008

Showing the first eight; more decompositions exist.
