Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 479900, here are decompositions:

19 + 479881 = 479900
61 + 479839 = 479900
67 + 479833 = 479900
79 + 479821 = 479900
103 + 479797 = 479900
139 + 479761 = 479900
151 + 479749 = 479900
199 + 479701 = 479900

Showing the first eight; more decompositions exist.
