Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489884, here are decompositions:

13 + 489871 = 489884
37 + 489847 = 489884
61 + 489823 = 489884
67 + 489817 = 489884
151 + 489733 = 489884
193 + 489691 = 489884
211 + 489673 = 489884
271 + 489613 = 489884

Showing the first eight; more decompositions exist.
