Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998470, here are decompositions:

41 + 998429 = 998470
47 + 998423 = 998470
59 + 998411 = 998470
71 + 998399 = 998470
89 + 998381 = 998470
197 + 998273 = 998470
227 + 998243 = 998470
233 + 998237 = 998470

Showing the first eight; more decompositions exist.
