Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489958, here are decompositions:

17 + 489941 = 489958
47 + 489911 = 489958
71 + 489887 = 489958
89 + 489869 = 489958
107 + 489851 = 489958
167 + 489791 = 489958
197 + 489761 = 489958
269 + 489689 = 489958

Showing the first eight; more decompositions exist.
