Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166944, here are decompositions:

13 + 166931 = 166944
73 + 166871 = 166944
83 + 166861 = 166944
97 + 166847 = 166944
101 + 166843 = 166944
103 + 166841 = 166944
137 + 166807 = 166944
163 + 166781 = 166944

Showing the first eight; more decompositions exist.
