Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490342, here are decompositions:

3 + 490339 = 490342
29 + 490313 = 490342
59 + 490283 = 490342
71 + 490271 = 490342
101 + 490241 = 490342
173 + 490169 = 490342
191 + 490151 = 490342
239 + 490103 = 490342

Showing the first eight; more decompositions exist.
