Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490492, here are decompositions:

11 + 490481 = 490492
29 + 490463 = 490492
71 + 490421 = 490492
179 + 490313 = 490492
251 + 490241 = 490492
269 + 490223 = 490492
389 + 490103 = 490492
461 + 490031 = 490492

Showing the first eight; more decompositions exist.
