Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490418, here are decompositions:

79 + 490339 = 490418
109 + 490309 = 490418
151 + 490267 = 490418
211 + 490207 = 490418
307 + 490111 = 490418
457 + 489961 = 490418
547 + 489871 = 490418
571 + 489847 = 490418

Showing the first eight; more decompositions exist.
