Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166950, here are decompositions:

19 + 166931 = 166950
31 + 166919 = 166950
41 + 166909 = 166950
79 + 166871 = 166950
83 + 166867 = 166950
89 + 166861 = 166950
97 + 166853 = 166950
101 + 166849 = 166950

Showing the first eight; more decompositions exist.
