Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489988, here are decompositions:

11 + 489977 = 489988
29 + 489959 = 489988
47 + 489941 = 489988
101 + 489887 = 489988
137 + 489851 = 489988
197 + 489791 = 489988
227 + 489761 = 489988
311 + 489677 = 489988

Showing the first eight; more decompositions exist.
