Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490254, here are decompositions:

5 + 490249 = 490254
7 + 490247 = 490254
13 + 490241 = 490254
31 + 490223 = 490254
47 + 490207 = 490254
53 + 490201 = 490254
71 + 490183 = 490254
103 + 490151 = 490254

Showing the first eight; more decompositions exist.
