Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489822, here are decompositions:

5 + 489817 = 489822
19 + 489803 = 489822
23 + 489799 = 489822
29 + 489793 = 489822
31 + 489791 = 489822
61 + 489761 = 489822
79 + 489743 = 489822
89 + 489733 = 489822

Showing the first eight; more decompositions exist.
