Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499980, here are decompositions:

7 + 499973 = 499980
11 + 499969 = 499980
23 + 499957 = 499980
37 + 499943 = 499980
53 + 499927 = 499980
83 + 499897 = 499980
97 + 499883 = 499980
101 + 499879 = 499980

Showing the first eight; more decompositions exist.
