Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998936, here are decompositions:

19 + 998917 = 998936
79 + 998857 = 998936
97 + 998839 = 998936
157 + 998779 = 998936
193 + 998743 = 998936
199 + 998737 = 998936
283 + 998653 = 998936
307 + 998629 = 998936

Showing the first eight; more decompositions exist.
