Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489882, here are decompositions:

11 + 489871 = 489882
13 + 489869 = 489882
31 + 489851 = 489882
59 + 489823 = 489882
79 + 489803 = 489882
83 + 489799 = 489882
89 + 489793 = 489882
139 + 489743 = 489882

Showing the first eight; more decompositions exist.
