Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489474, here are decompositions:

17 + 489457 = 489474
43 + 489431 = 489474
47 + 489427 = 489474
67 + 489407 = 489474
107 + 489367 = 489474
113 + 489361 = 489474
131 + 489343 = 489474
137 + 489337 = 489474

Showing the first eight; more decompositions exist.
