Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490788, here are decompositions:

5 + 490783 = 490788
17 + 490771 = 490788
19 + 490769 = 490788
47 + 490741 = 490788
127 + 490661 = 490788
157 + 490631 = 490788
197 + 490591 = 490788
211 + 490577 = 490788

Showing the first eight; more decompositions exist.
