Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489968, here are decompositions:

7 + 489961 = 489968
67 + 489901 = 489968
97 + 489871 = 489968
151 + 489817 = 489968
277 + 489691 = 489968
337 + 489631 = 489968
397 + 489571 = 489968
439 + 489529 = 489968

Showing the first eight; more decompositions exist.
