Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169946, here are decompositions:

3 + 169943 = 169946
13 + 169933 = 169946
37 + 169909 = 169946
103 + 169843 = 169946
109 + 169837 = 169946
157 + 169789 = 169946
163 + 169783 = 169946
193 + 169753 = 169946

Showing the first eight; more decompositions exist.
