Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490148, here are decompositions:

31 + 490117 = 490148
37 + 490111 = 490148
277 + 489871 = 490148
331 + 489817 = 490148
349 + 489799 = 490148
457 + 489691 = 490148
577 + 489571 = 490148
619 + 489529 = 490148

Showing the first eight; more decompositions exist.
