Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998798, here are decompositions:

19 + 998779 = 998798
61 + 998737 = 998798
109 + 998689 = 998798
181 + 998617 = 998798
271 + 998527 = 998798
379 + 998419 = 998798
421 + 998377 = 998798
487 + 998311 = 998798

Showing the first eight; more decompositions exist.
