Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489778, here are decompositions:

17 + 489761 = 489778
89 + 489689 = 489778
101 + 489677 = 489778
227 + 489551 = 489778
239 + 489539 = 489778
347 + 489431 = 489778
389 + 489389 = 489778
449 + 489329 = 489778

Showing the first eight; more decompositions exist.
