Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998396, here are decompositions:

19 + 998377 = 998396
43 + 998353 = 998396
67 + 998329 = 998396
109 + 998287 = 998396
199 + 998197 = 998396
229 + 998167 = 998396
313 + 998083 = 998396
367 + 998029 = 998396

Showing the first eight; more decompositions exist.
