Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166112, here are decompositions:

13 + 166099 = 166112
31 + 166081 = 166112
151 + 165961 = 166112
181 + 165931 = 166112
211 + 165901 = 166112
229 + 165883 = 166112
283 + 165829 = 166112
313 + 165799 = 166112

Showing the first eight; more decompositions exist.
