Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998038, here are decompositions:

11 + 998027 = 998038
29 + 998009 = 998038
47 + 997991 = 998038
89 + 997949 = 998038
149 + 997889 = 998038
227 + 997811 = 998038
269 + 997769 = 998038
311 + 997727 = 998038

Showing the first eight; more decompositions exist.
