Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489030, here are decompositions:

11 + 489019 = 489030
19 + 489011 = 489030
29 + 489001 = 489030
37 + 488993 = 489030
71 + 488959 = 489030
83 + 488947 = 489030
109 + 488921 = 489030
137 + 488893 = 489030

Showing the first eight; more decompositions exist.
