Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490218, here are decompositions:

11 + 490207 = 490218
17 + 490201 = 490218
59 + 490159 = 490218
67 + 490151 = 490218
97 + 490121 = 490218
101 + 490117 = 490218
107 + 490111 = 490218
199 + 490019 = 490218

Showing the first eight; more decompositions exist.
