Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490866, here are decompositions:

7 + 490859 = 490866
17 + 490849 = 490866
29 + 490837 = 490866
37 + 490829 = 490866
83 + 490783 = 490866
97 + 490769 = 490866
223 + 490643 = 490866
239 + 490627 = 490866

Showing the first eight; more decompositions exist.
