Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490804, here are decompositions:

71 + 490733 = 490804
107 + 490697 = 490804
173 + 490631 = 490804
227 + 490577 = 490804
233 + 490571 = 490804
263 + 490541 = 490804
311 + 490493 = 490804
383 + 490421 = 490804

Showing the first eight; more decompositions exist.
