Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998644, here are decompositions:

11 + 998633 = 998644
83 + 998561 = 998644
107 + 998537 = 998644
131 + 998513 = 998644
173 + 998471 = 998644
233 + 998411 = 998644
263 + 998381 = 998644
401 + 998243 = 998644

Showing the first eight; more decompositions exist.
