Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490732, here are decompositions:

71 + 490661 = 490732
89 + 490643 = 490732
101 + 490631 = 490732
113 + 490619 = 490732
173 + 490559 = 490732
191 + 490541 = 490732
233 + 490499 = 490732
239 + 490493 = 490732

Showing the first eight; more decompositions exist.
