Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998284, here are decompositions:

3 + 998281 = 998284
11 + 998273 = 998284
41 + 998243 = 998284
47 + 998237 = 998284
71 + 998213 = 998284
83 + 998201 = 998284
137 + 998147 = 998284
167 + 998117 = 998284

Showing the first eight; more decompositions exist.
