Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490450, here are decompositions:

29 + 490421 = 490450
83 + 490367 = 490450
137 + 490313 = 490450
167 + 490283 = 490450
173 + 490277 = 490450
179 + 490271 = 490450
227 + 490223 = 490450
281 + 490169 = 490450

Showing the first eight; more decompositions exist.
