Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489258, here are decompositions:

17 + 489241 = 489258
19 + 489239 = 489258
41 + 489217 = 489258
61 + 489197 = 489258
67 + 489191 = 489258
79 + 489179 = 489258
97 + 489161 = 489258
101 + 489157 = 489258

Showing the first eight; more decompositions exist.
