Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490822, here are decompositions:

53 + 490769 = 490822
89 + 490733 = 490822
179 + 490643 = 490822
191 + 490631 = 490822
251 + 490571 = 490822
263 + 490559 = 490822
281 + 490541 = 490822
359 + 490463 = 490822

Showing the first eight; more decompositions exist.
