Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489072, here are decompositions:

11 + 489061 = 489072
19 + 489053 = 489072
29 + 489043 = 489072
53 + 489019 = 489072
61 + 489011 = 489072
71 + 489001 = 489072
79 + 488993 = 489072
113 + 488959 = 489072

Showing the first eight; more decompositions exist.
