Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490260, here are decompositions:

11 + 490249 = 490260
13 + 490247 = 490260
19 + 490241 = 490260
37 + 490223 = 490260
53 + 490207 = 490260
59 + 490201 = 490260
101 + 490159 = 490260
109 + 490151 = 490260

Showing the first eight; more decompositions exist.
