Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490428, here are decompositions:

7 + 490421 = 490428
11 + 490417 = 490428
61 + 490367 = 490428
89 + 490339 = 490428
151 + 490277 = 490428
157 + 490271 = 490428
179 + 490249 = 490428
181 + 490247 = 490428

Showing the first eight; more decompositions exist.
