Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489836, here are decompositions:

3 + 489833 = 489836
13 + 489823 = 489836
19 + 489817 = 489836
37 + 489799 = 489836
43 + 489793 = 489836
103 + 489733 = 489836
157 + 489679 = 489836
163 + 489673 = 489836

Showing the first eight; more decompositions exist.
