Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999858, here are decompositions:

5 + 999853 = 999858
89 + 999769 = 999858
109 + 999749 = 999858
131 + 999727 = 999858
137 + 999721 = 999858
191 + 999667 = 999858
227 + 999631 = 999858
317 + 999541 = 999858

Showing the first eight; more decompositions exist.
