Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998870, here are decompositions:

13 + 998857 = 998870
31 + 998839 = 998870
127 + 998743 = 998870
181 + 998689 = 998870
241 + 998629 = 998870
331 + 998539 = 998870
373 + 998497 = 998870
541 + 998329 = 998870

Showing the first eight; more decompositions exist.
