Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490658, here are decompositions:

31 + 490627 = 490658
67 + 490591 = 490658
79 + 490579 = 490658
109 + 490549 = 490658
139 + 490519 = 490658
199 + 490459 = 490658
241 + 490417 = 490658
349 + 490309 = 490658

Showing the first eight; more decompositions exist.
