Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489682, here are decompositions:

3 + 489679 = 489682
5 + 489677 = 489682
23 + 489659 = 489682
29 + 489653 = 489682
131 + 489551 = 489682
233 + 489449 = 489682
251 + 489431 = 489682
293 + 489389 = 489682

Showing the first eight; more decompositions exist.
