Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489028, here are decompositions:

17 + 489011 = 489028
47 + 488981 = 489028
107 + 488921 = 489028
131 + 488897 = 489028
149 + 488879 = 489028
167 + 488861 = 489028
269 + 488759 = 489028
311 + 488717 = 489028

Showing the first eight; more decompositions exist.
