Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489898, here are decompositions:

11 + 489887 = 489898
29 + 489869 = 489898
47 + 489851 = 489898
107 + 489791 = 489898
137 + 489761 = 489898
239 + 489659 = 489898
347 + 489551 = 489898
359 + 489539 = 489898

Showing the first eight; more decompositions exist.
