Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490884, here are decompositions:

7 + 490877 = 490884
47 + 490837 = 490884
101 + 490783 = 490884
113 + 490771 = 490884
151 + 490733 = 490884
223 + 490661 = 490884
241 + 490643 = 490884
257 + 490627 = 490884

Showing the first eight; more decompositions exist.
