Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662198, here are decompositions:

11 + 8662187 = 8662198
29 + 8662169 = 8662198
47 + 8662151 = 8662198
71 + 8662127 = 8662198
89 + 8662109 = 8662198
107 + 8662091 = 8662198
179 + 8662019 = 8662198
257 + 8661941 = 8662198

Showing the first eight; more decompositions exist.
