Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166494, here are decompositions:

7 + 166487 = 166494
23 + 166471 = 166494
37 + 166457 = 166494
101 + 166393 = 166494
131 + 166363 = 166494
137 + 166357 = 166494
191 + 166303 = 166494
193 + 166301 = 166494

Showing the first eight; more decompositions exist.
