Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166576, here are decompositions:

5 + 166571 = 166576
89 + 166487 = 166576
167 + 166409 = 166576
173 + 166403 = 166576
227 + 166349 = 166576
257 + 166319 = 166576
317 + 166259 = 166576
419 + 166157 = 166576

Showing the first eight; more decompositions exist.
