Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499866, here are decompositions:

13 + 499853 = 499866
47 + 499819 = 499866
79 + 499787 = 499866
127 + 499739 = 499866
137 + 499729 = 499866
149 + 499717 = 499866
173 + 499693 = 499866
179 + 499687 = 499866

Showing the first eight; more decompositions exist.
