Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489388, here are decompositions:

59 + 489329 = 489388
89 + 489299 = 489388
131 + 489257 = 489388
149 + 489239 = 489388
191 + 489197 = 489388
197 + 489191 = 489388
227 + 489161 = 489388
467 + 488921 = 489388

Showing the first eight; more decompositions exist.
