Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166968, here are decompositions:

19 + 166949 = 166968
37 + 166931 = 166968
59 + 166909 = 166968
97 + 166871 = 166968
101 + 166867 = 166968
107 + 166861 = 166968
127 + 166841 = 166968
227 + 166741 = 166968

Showing the first eight; more decompositions exist.
