Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722198, here are decompositions:

5 + 8722193 = 8722198
11 + 8722187 = 8722198
29 + 8722169 = 8722198
101 + 8722097 = 8722198
179 + 8722019 = 8722198
197 + 8722001 = 8722198
257 + 8721941 = 8722198
269 + 8721929 = 8722198

Showing the first eight; more decompositions exist.
