Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489642, here are decompositions:

11 + 489631 = 489642
29 + 489613 = 489642
71 + 489571 = 489642
89 + 489553 = 489642
103 + 489539 = 489642
113 + 489529 = 489642
149 + 489493 = 489642
163 + 489479 = 489642

Showing the first eight; more decompositions exist.
