Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166010, here are decompositions:

79 + 165931 = 166010
109 + 165901 = 166010
127 + 165883 = 166010
181 + 165829 = 166010
193 + 165817 = 166010
199 + 165811 = 166010
211 + 165799 = 166010
307 + 165703 = 166010

Showing the first eight; more decompositions exist.
