Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489916, here are decompositions:

3 + 489913 = 489916
5 + 489911 = 489916
29 + 489887 = 489916
47 + 489869 = 489916
83 + 489833 = 489916
113 + 489803 = 489916
173 + 489743 = 489916
227 + 489689 = 489916

Showing the first eight; more decompositions exist.
