Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490252, here are decompositions:

3 + 490249 = 490252
5 + 490247 = 490252
11 + 490241 = 490252
29 + 490223 = 490252
83 + 490169 = 490252
101 + 490151 = 490252
131 + 490121 = 490252
149 + 490103 = 490252

Showing the first eight; more decompositions exist.
