Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 486490, here are decompositions:

41 + 486449 = 486490
47 + 486443 = 486490
83 + 486407 = 486490
101 + 486389 = 486490
113 + 486377 = 486490
149 + 486341 = 486490
167 + 486323 = 486490
197 + 486293 = 486490

Showing the first eight; more decompositions exist.
