Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490888, here are decompositions:

11 + 490877 = 490888
29 + 490859 = 490888
59 + 490829 = 490888
191 + 490697 = 490888
227 + 490661 = 490888
257 + 490631 = 490888
269 + 490619 = 490888
311 + 490577 = 490888

Showing the first eight; more decompositions exist.
