Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490208, here are decompositions:

7 + 490201 = 490208
97 + 490111 = 490208
151 + 490057 = 490208
307 + 489901 = 490208
337 + 489871 = 490208
409 + 489799 = 490208
577 + 489631 = 490208
751 + 489457 = 490208

Showing the first eight; more decompositions exist.
