Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998900, here are decompositions:

3 + 998897 = 998900
43 + 998857 = 998900
61 + 998839 = 998900
151 + 998749 = 998900
157 + 998743 = 998900
163 + 998737 = 998900
211 + 998689 = 998900
271 + 998629 = 998900

Showing the first eight; more decompositions exist.
