Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499806, here are decompositions:

5 + 499801 = 499806
19 + 499787 = 499806
59 + 499747 = 499806
67 + 499739 = 499806
89 + 499717 = 499806
113 + 499693 = 499806
127 + 499679 = 499806
137 + 499669 = 499806

Showing the first eight; more decompositions exist.
