Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489928, here are decompositions:

17 + 489911 = 489928
41 + 489887 = 489928
59 + 489869 = 489928
137 + 489791 = 489928
167 + 489761 = 489928
239 + 489689 = 489928
251 + 489677 = 489928
269 + 489659 = 489928

Showing the first eight; more decompositions exist.
