Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998736, here are decompositions:

19 + 998717 = 998736
47 + 998689 = 998736
83 + 998653 = 998736
103 + 998633 = 998736
107 + 998629 = 998736
113 + 998623 = 998736
197 + 998539 = 998736
199 + 998537 = 998736

Showing the first eight; more decompositions exist.
