Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998398, here are decompositions:

17 + 998381 = 998398
179 + 998219 = 998398
197 + 998201 = 998398
251 + 998147 = 998398
281 + 998117 = 998398
389 + 998009 = 998398
449 + 997949 = 998398
509 + 997889 = 998398

Showing the first eight; more decompositions exist.
