Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499040, here are decompositions:

7 + 499033 = 499040
13 + 499027 = 499040
19 + 499021 = 499040
67 + 498973 = 499040
79 + 498961 = 499040
103 + 498937 = 499040
109 + 498931 = 499040
181 + 498859 = 499040

Showing the first eight; more decompositions exist.
