Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028198, here are decompositions:

7 + 1028191 = 1028198
97 + 1028101 = 1028198
109 + 1028089 = 1028198
151 + 1028047 = 1028198
181 + 1028017 = 1028198
211 + 1027987 = 1028198
229 + 1027969 = 1028198
307 + 1027891 = 1028198

Showing the first eight; more decompositions exist.
