Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489850, here are decompositions:

3 + 489847 = 489850
17 + 489833 = 489850
47 + 489803 = 489850
59 + 489791 = 489850
89 + 489761 = 489850
107 + 489743 = 489850
173 + 489677 = 489850
191 + 489659 = 489850

Showing the first eight; more decompositions exist.
