Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489816, here are decompositions:

13 + 489803 = 489816
17 + 489799 = 489816
23 + 489793 = 489816
73 + 489743 = 489816
83 + 489733 = 489816
127 + 489689 = 489816
137 + 489679 = 489816
139 + 489677 = 489816

Showing the first eight; more decompositions exist.
