Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489748, here are decompositions:

5 + 489743 = 489748
59 + 489689 = 489748
71 + 489677 = 489748
89 + 489659 = 489748
191 + 489557 = 489748
197 + 489551 = 489748
269 + 489479 = 489748
317 + 489431 = 489748

Showing the first eight; more decompositions exist.
