Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166850, here are decompositions:

3 + 166847 = 166850
7 + 166843 = 166850
43 + 166807 = 166850
67 + 166783 = 166850
109 + 166741 = 166850
127 + 166723 = 166850
157 + 166693 = 166850
181 + 166669 = 166850

Showing the first eight; more decompositions exist.
