Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490344, here are decompositions:

5 + 490339 = 490344
31 + 490313 = 490344
61 + 490283 = 490344
67 + 490277 = 490344
73 + 490271 = 490344
97 + 490247 = 490344
103 + 490241 = 490344
137 + 490207 = 490344

Showing the first eight; more decompositions exist.
