Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489018, here are decompositions:

7 + 489011 = 489018
17 + 489001 = 489018
37 + 488981 = 489018
59 + 488959 = 489018
71 + 488947 = 489018
97 + 488921 = 489018
109 + 488909 = 489018
139 + 488879 = 489018

Showing the first eight; more decompositions exist.
