Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998432, here are decompositions:

3 + 998429 = 998432
13 + 998419 = 998432
79 + 998353 = 998432
103 + 998329 = 998432
151 + 998281 = 998432
271 + 998161 = 998432
349 + 998083 = 998432
499 + 997933 = 998432

Showing the first eight; more decompositions exist.
