Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166946, here are decompositions:

37 + 166909 = 166946
79 + 166867 = 166946
97 + 166849 = 166946
103 + 166843 = 166946
139 + 166807 = 166946
163 + 166783 = 166946
223 + 166723 = 166946
277 + 166669 = 166946

Showing the first eight; more decompositions exist.
