Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489664, here are decompositions:

5 + 489659 = 489664
11 + 489653 = 489664
107 + 489557 = 489664
113 + 489551 = 489664
233 + 489431 = 489664
257 + 489407 = 489664
401 + 489263 = 489664
467 + 489197 = 489664

Showing the first eight; more decompositions exist.
