Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998884, here are decompositions:

23 + 998861 = 998884
41 + 998843 = 998884
53 + 998831 = 998884
71 + 998813 = 998884
167 + 998717 = 998884
197 + 998687 = 998884
233 + 998651 = 998884
251 + 998633 = 998884

Showing the first eight; more decompositions exist.
