Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489690, here are decompositions:

11 + 489679 = 489690
13 + 489677 = 489690
17 + 489673 = 489690
31 + 489659 = 489690
37 + 489653 = 489690
59 + 489631 = 489690
137 + 489553 = 489690
139 + 489551 = 489690

Showing the first eight; more decompositions exist.
