Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998306, here are decompositions:

19 + 998287 = 998306
109 + 998197 = 998306
139 + 998167 = 998306
223 + 998083 = 998306
229 + 998077 = 998306
277 + 998029 = 998306
373 + 997933 = 998306
409 + 997897 = 998306

Showing the first eight; more decompositions exist.
