Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166374, here are decompositions:

11 + 166363 = 166374
17 + 166357 = 166374
23 + 166351 = 166374
71 + 166303 = 166374
73 + 166301 = 166374
101 + 166273 = 166374
127 + 166247 = 166374
137 + 166237 = 166374

Showing the first eight; more decompositions exist.
