Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489874, here are decompositions:

3 + 489871 = 489874
5 + 489869 = 489874
23 + 489851 = 489874
41 + 489833 = 489874
71 + 489803 = 489874
83 + 489791 = 489874
113 + 489761 = 489874
131 + 489743 = 489874

Showing the first eight; more decompositions exist.
