Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489618, here are decompositions:

5 + 489613 = 489618
47 + 489571 = 489618
61 + 489557 = 489618
67 + 489551 = 489618
79 + 489539 = 489618
89 + 489529 = 489618
131 + 489487 = 489618
139 + 489479 = 489618

Showing the first eight; more decompositions exist.
