Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489340, here are decompositions:

3 + 489337 = 489340
11 + 489329 = 489340
41 + 489299 = 489340
83 + 489257 = 489340
101 + 489239 = 489340
149 + 489191 = 489340
179 + 489161 = 489340
227 + 489113 = 489340

Showing the first eight; more decompositions exist.
