Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489756, here are decompositions:

13 + 489743 = 489756
23 + 489733 = 489756
67 + 489689 = 489756
79 + 489677 = 489756
83 + 489673 = 489756
97 + 489659 = 489756
103 + 489653 = 489756
199 + 489557 = 489756

Showing the first eight; more decompositions exist.
