Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490268, here are decompositions:

19 + 490249 = 490268
61 + 490207 = 490268
67 + 490201 = 490268
109 + 490159 = 490268
151 + 490117 = 490268
157 + 490111 = 490268
211 + 490057 = 490268
307 + 489961 = 490268

Showing the first eight; more decompositions exist.
