Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489948, here are decompositions:

5 + 489943 = 489948
7 + 489941 = 489948
37 + 489911 = 489948
47 + 489901 = 489948
61 + 489887 = 489948
79 + 489869 = 489948
97 + 489851 = 489948
101 + 489847 = 489948

Showing the first eight; more decompositions exist.
