Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998868, here are decompositions:

7 + 998861 = 998868
11 + 998857 = 998868
29 + 998839 = 998868
37 + 998831 = 998868
89 + 998779 = 998868
109 + 998759 = 998868
131 + 998737 = 998868
151 + 998717 = 998868

Showing the first eight; more decompositions exist.
