Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490338, here are decompositions:

29 + 490309 = 490338
61 + 490277 = 490338
67 + 490271 = 490338
71 + 490267 = 490338
89 + 490249 = 490338
97 + 490241 = 490338
131 + 490207 = 490338
137 + 490201 = 490338

Showing the first eight; more decompositions exist.
