Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490756, here are decompositions:

23 + 490733 = 490756
59 + 490697 = 490756
113 + 490643 = 490756
137 + 490619 = 490756
179 + 490577 = 490756
197 + 490559 = 490756
257 + 490499 = 490756
263 + 490493 = 490756

Showing the first eight; more decompositions exist.
