Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489666, here are decompositions:

7 + 489659 = 489666
13 + 489653 = 489666
53 + 489613 = 489666
109 + 489557 = 489666
113 + 489553 = 489666
127 + 489539 = 489666
137 + 489529 = 489666
173 + 489493 = 489666

Showing the first eight; more decompositions exist.
