Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998858, here are decompositions:

19 + 998839 = 998858
79 + 998779 = 998858
109 + 998749 = 998858
229 + 998629 = 998858
241 + 998617 = 998858
307 + 998551 = 998858
331 + 998527 = 998858
439 + 998419 = 998858

Showing the first eight; more decompositions exist.
