Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490280, here are decompositions:

3 + 490277 = 490280
13 + 490267 = 490280
31 + 490249 = 490280
73 + 490207 = 490280
79 + 490201 = 490280
97 + 490183 = 490280
163 + 490117 = 490280
223 + 490057 = 490280

Showing the first eight; more decompositions exist.
