Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998828, here are decompositions:

79 + 998749 = 998828
139 + 998689 = 998828
199 + 998629 = 998828
211 + 998617 = 998828
277 + 998551 = 998828
331 + 998497 = 998828
409 + 998419 = 998828
499 + 998329 = 998828

Showing the first eight; more decompositions exist.
