Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490898, here are decompositions:

7 + 490891 = 490898
61 + 490837 = 490898
127 + 490771 = 490898
157 + 490741 = 490898
271 + 490627 = 490898
307 + 490591 = 490898
349 + 490549 = 490898
379 + 490519 = 490898

Showing the first eight; more decompositions exist.
