Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490272, here are decompositions:

5 + 490267 = 490272
23 + 490249 = 490272
31 + 490241 = 490272
71 + 490201 = 490272
89 + 490183 = 490272
103 + 490169 = 490272
113 + 490159 = 490272
151 + 490121 = 490272

Showing the first eight; more decompositions exist.
