Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489880, here are decompositions:

11 + 489869 = 489880
29 + 489851 = 489880
47 + 489833 = 489880
89 + 489791 = 489880
137 + 489743 = 489880
191 + 489689 = 489880
227 + 489653 = 489880
401 + 489479 = 489880

Showing the first eight; more decompositions exist.
