Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489558, here are decompositions:

5 + 489553 = 489558
7 + 489551 = 489558
19 + 489539 = 489558
29 + 489529 = 489558
71 + 489487 = 489558
79 + 489479 = 489558
101 + 489457 = 489558
109 + 489449 = 489558

Showing the first eight; more decompositions exist.
