Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998538, here are decompositions:

11 + 998527 = 998538
41 + 998497 = 998538
67 + 998471 = 998538
109 + 998429 = 998538
127 + 998411 = 998538
139 + 998399 = 998538
157 + 998381 = 998538
227 + 998311 = 998538

Showing the first eight; more decompositions exist.
