Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490438, here are decompositions:

17 + 490421 = 490438
71 + 490367 = 490438
167 + 490271 = 490438
191 + 490247 = 490438
197 + 490241 = 490438
269 + 490169 = 490438
317 + 490121 = 490438
419 + 490019 = 490438

Showing the first eight; more decompositions exist.
