Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998506, here are decompositions:

83 + 998423 = 998506
107 + 998399 = 998506
233 + 998273 = 998506
263 + 998243 = 998506
269 + 998237 = 998506
293 + 998213 = 998506
359 + 998147 = 998506
389 + 998117 = 998506

Showing the first eight; more decompositions exist.
