Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179450, here are decompositions:

13 + 179437 = 179450
43 + 179407 = 179450
67 + 179383 = 179450
163 + 179287 = 179450
181 + 179269 = 179450
241 + 179209 = 179450
277 + 179173 = 179450
283 + 179167 = 179450

Showing the first eight; more decompositions exist.
