Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490810, here are decompositions:

41 + 490769 = 490810
113 + 490697 = 490810
149 + 490661 = 490810
167 + 490643 = 490810
179 + 490631 = 490810
191 + 490619 = 490810
233 + 490577 = 490810
239 + 490571 = 490810

Showing the first eight; more decompositions exist.
