Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166028, here are decompositions:

7 + 166021 = 166028
67 + 165961 = 166028
97 + 165931 = 166028
127 + 165901 = 166028
151 + 165877 = 166028
199 + 165829 = 166028
211 + 165817 = 166028
229 + 165799 = 166028

Showing the first eight; more decompositions exist.
