Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998908, here are decompositions:

11 + 998897 = 998908
47 + 998861 = 998908
89 + 998819 = 998908
149 + 998759 = 998908
191 + 998717 = 998908
227 + 998681 = 998908
257 + 998651 = 998908
347 + 998561 = 998908

Showing the first eight; more decompositions exist.
