Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166910, here are decompositions:

43 + 166867 = 166910
61 + 166849 = 166910
67 + 166843 = 166910
103 + 166807 = 166910
127 + 166783 = 166910
241 + 166669 = 166910
283 + 166627 = 166910
307 + 166603 = 166910

Showing the first eight; more decompositions exist.
