Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489950, here are decompositions:

7 + 489943 = 489950
37 + 489913 = 489950
79 + 489871 = 489950
103 + 489847 = 489950
127 + 489823 = 489950
151 + 489799 = 489950
157 + 489793 = 489950
271 + 489679 = 489950

Showing the first eight; more decompositions exist.
