Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499872, here are decompositions:

19 + 499853 = 499872
53 + 499819 = 499872
71 + 499801 = 499872
179 + 499693 = 499872
181 + 499691 = 499872
193 + 499679 = 499872
199 + 499673 = 499872
211 + 499661 = 499872

Showing the first eight; more decompositions exist.
