Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490498, here are decompositions:

5 + 490493 = 490498
17 + 490481 = 490498
131 + 490367 = 490498
227 + 490271 = 490498
251 + 490247 = 490498
257 + 490241 = 490498
347 + 490151 = 490498
401 + 490097 = 490498

Showing the first eight; more decompositions exist.
