Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166432, here are decompositions:

3 + 166429 = 166432
23 + 166409 = 166432
29 + 166403 = 166432
83 + 166349 = 166432
113 + 166319 = 166432
131 + 166301 = 166432
173 + 166259 = 166432
263 + 166169 = 166432

Showing the first eight; more decompositions exist.
