Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998440, here are decompositions:

11 + 998429 = 998440
17 + 998423 = 998440
29 + 998411 = 998440
41 + 998399 = 998440
59 + 998381 = 998440
167 + 998273 = 998440
197 + 998243 = 998440
227 + 998213 = 998440

Showing the first eight; more decompositions exist.
