Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163450, here are decompositions:

17 + 163433 = 163450
41 + 163409 = 163450
47 + 163403 = 163450
83 + 163367 = 163450
113 + 163337 = 163450
191 + 163259 = 163450
227 + 163223 = 163450
239 + 163211 = 163450

Showing the first eight; more decompositions exist.
