Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998698, here are decompositions:

11 + 998687 = 998698
17 + 998681 = 998698
47 + 998651 = 998698
137 + 998561 = 998698
227 + 998471 = 998698
269 + 998429 = 998698
317 + 998381 = 998698
461 + 998237 = 998698

Showing the first eight; more decompositions exist.
