Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490468, here are decompositions:

5 + 490463 = 490468
47 + 490421 = 490468
101 + 490367 = 490468
191 + 490277 = 490468
197 + 490271 = 490468
227 + 490241 = 490468
317 + 490151 = 490468
347 + 490121 = 490468

Showing the first eight; more decompositions exist.
