Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166370, here are decompositions:

7 + 166363 = 166370
13 + 166357 = 166370
19 + 166351 = 166370
67 + 166303 = 166370
73 + 166297 = 166370
97 + 166273 = 166370
151 + 166219 = 166370
163 + 166207 = 166370

Showing the first eight; more decompositions exist.
