Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998408, here are decompositions:

31 + 998377 = 998408
79 + 998329 = 998408
97 + 998311 = 998408
127 + 998281 = 998408
211 + 998197 = 998408
241 + 998167 = 998408
331 + 998077 = 998408
337 + 998071 = 998408

Showing the first eight; more decompositions exist.
