Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489724, here are decompositions:

47 + 489677 = 489724
71 + 489653 = 489724
167 + 489557 = 489724
173 + 489551 = 489724
293 + 489431 = 489724
317 + 489407 = 489724
461 + 489263 = 489724
467 + 489257 = 489724

Showing the first eight; more decompositions exist.
