Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166448, here are decompositions:

19 + 166429 = 166448
31 + 166417 = 166448
97 + 166351 = 166448
151 + 166297 = 166448
211 + 166237 = 166448
229 + 166219 = 166448
241 + 166207 = 166448
349 + 166099 = 166448

Showing the first eight; more decompositions exist.
