Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998826, here are decompositions:

7 + 998819 = 998826
13 + 998813 = 998826
47 + 998779 = 998826
67 + 998759 = 998826
83 + 998743 = 998826
89 + 998737 = 998826
109 + 998717 = 998826
137 + 998689 = 998826

Showing the first eight; more decompositions exist.
