Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499920, here are decompositions:

17 + 499903 = 499920
23 + 499897 = 499920
37 + 499883 = 499920
41 + 499879 = 499920
67 + 499853 = 499920
101 + 499819 = 499920
139 + 499781 = 499920
173 + 499747 = 499920

Showing the first eight; more decompositions exist.
