Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490460, here are decompositions:

7 + 490453 = 490460
43 + 490417 = 490460
67 + 490393 = 490460
151 + 490309 = 490460
193 + 490267 = 490460
211 + 490249 = 490460
277 + 490183 = 490460
349 + 490111 = 490460

Showing the first eight; more decompositions exist.
