Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489646, here are decompositions:

89 + 489557 = 489646
107 + 489539 = 489646
167 + 489479 = 489646
197 + 489449 = 489646
239 + 489407 = 489646
257 + 489389 = 489646
317 + 489329 = 489646
347 + 489299 = 489646

Showing the first eight; more decompositions exist.
