Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489672, here are decompositions:

13 + 489659 = 489672
19 + 489653 = 489672
41 + 489631 = 489672
59 + 489613 = 489672
101 + 489571 = 489672
179 + 489493 = 489672
193 + 489479 = 489672
223 + 489449 = 489672

Showing the first eight; more decompositions exist.
