Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489860, here are decompositions:

13 + 489847 = 489860
37 + 489823 = 489860
43 + 489817 = 489860
61 + 489799 = 489860
67 + 489793 = 489860
127 + 489733 = 489860
181 + 489679 = 489860
229 + 489631 = 489860

Showing the first eight; more decompositions exist.
