Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489978, here are decompositions:

17 + 489961 = 489978
19 + 489959 = 489978
37 + 489941 = 489978
67 + 489911 = 489978
107 + 489871 = 489978
109 + 489869 = 489978
127 + 489851 = 489978
131 + 489847 = 489978

Showing the first eight; more decompositions exist.
