Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166956, here are decompositions:

7 + 166949 = 166956
37 + 166919 = 166956
47 + 166909 = 166956
89 + 166867 = 166956
103 + 166853 = 166956
107 + 166849 = 166956
109 + 166847 = 166956
113 + 166843 = 166956

Showing the first eight; more decompositions exist.
