Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490648, here are decompositions:

5 + 490643 = 490648
17 + 490631 = 490648
29 + 490619 = 490648
71 + 490577 = 490648
89 + 490559 = 490648
107 + 490541 = 490648
149 + 490499 = 490648
167 + 490481 = 490648

Showing the first eight; more decompositions exist.
