Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490266, here are decompositions:

17 + 490249 = 490266
19 + 490247 = 490266
43 + 490223 = 490266
59 + 490207 = 490266
83 + 490183 = 490266
97 + 490169 = 490266
107 + 490159 = 490266
149 + 490117 = 490266

Showing the first eight; more decompositions exist.
