Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489644, here are decompositions:

13 + 489631 = 489644
31 + 489613 = 489644
73 + 489571 = 489644
151 + 489493 = 489644
157 + 489487 = 489644
277 + 489367 = 489644
283 + 489361 = 489644
307 + 489337 = 489644

Showing the first eight; more decompositions exist.
