Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489828, here are decompositions:

5 + 489823 = 489828
11 + 489817 = 489828
29 + 489799 = 489828
37 + 489791 = 489828
67 + 489761 = 489828
137 + 489691 = 489828
139 + 489689 = 489828
149 + 489679 = 489828

Showing the first eight; more decompositions exist.
