Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490628, here are decompositions:

37 + 490591 = 490628
79 + 490549 = 490628
109 + 490519 = 490628
211 + 490417 = 490628
379 + 490249 = 490628
421 + 490207 = 490628
571 + 490057 = 490628
727 + 489901 = 490628

Showing the first eight; more decompositions exist.
