Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166284, here are decompositions:

11 + 166273 = 166284
37 + 166247 = 166284
47 + 166237 = 166284
101 + 166183 = 166284
127 + 166157 = 166284
137 + 166147 = 166284
241 + 166043 = 166284
257 + 166027 = 166284

Showing the first eight; more decompositions exist.
