Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998564, here are decompositions:

3 + 998561 = 998564
13 + 998551 = 998564
37 + 998527 = 998564
67 + 998497 = 998564
211 + 998353 = 998564
277 + 998287 = 998564
283 + 998281 = 998564
367 + 998197 = 998564

Showing the first eight; more decompositions exist.
