Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490480, here are decompositions:

17 + 490463 = 490480
59 + 490421 = 490480
113 + 490367 = 490480
167 + 490313 = 490480
197 + 490283 = 490480
233 + 490247 = 490480
239 + 490241 = 490480
257 + 490223 = 490480

Showing the first eight; more decompositions exist.
