Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490384, here are decompositions:

17 + 490367 = 490384
71 + 490313 = 490384
101 + 490283 = 490384
107 + 490277 = 490384
113 + 490271 = 490384
137 + 490247 = 490384
233 + 490151 = 490384
263 + 490121 = 490384

Showing the first eight; more decompositions exist.
