Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998428, here are decompositions:

5 + 998423 = 998428
17 + 998411 = 998428
29 + 998399 = 998428
47 + 998381 = 998428
191 + 998237 = 998428
227 + 998201 = 998428
281 + 998147 = 998428
311 + 998117 = 998428

Showing the first eight; more decompositions exist.
