Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489970, here are decompositions:

11 + 489959 = 489970
29 + 489941 = 489970
59 + 489911 = 489970
83 + 489887 = 489970
101 + 489869 = 489970
137 + 489833 = 489970
167 + 489803 = 489970
179 + 489791 = 489970

Showing the first eight; more decompositions exist.
