Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490224, here are decompositions:

17 + 490207 = 490224
23 + 490201 = 490224
41 + 490183 = 490224
73 + 490151 = 490224
103 + 490121 = 490224
107 + 490117 = 490224
113 + 490111 = 490224
127 + 490097 = 490224

Showing the first eight; more decompositions exist.
