Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998966, here are decompositions:

19 + 998947 = 998966
109 + 998857 = 998966
127 + 998839 = 998966
223 + 998743 = 998966
229 + 998737 = 998966
277 + 998689 = 998966
313 + 998653 = 998966
337 + 998629 = 998966

Showing the first eight; more decompositions exist.
