Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489318, here are decompositions:

19 + 489299 = 489318
61 + 489257 = 489318
79 + 489239 = 489318
101 + 489217 = 489318
127 + 489191 = 489318
139 + 489179 = 489318
157 + 489161 = 489318
191 + 489127 = 489318

Showing the first eight; more decompositions exist.
