Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668198, here are decompositions:

5 + 8668193 = 8668198
41 + 8668157 = 8668198
47 + 8668151 = 8668198
131 + 8668067 = 8668198
137 + 8668061 = 8668198
167 + 8668031 = 8668198
197 + 8668001 = 8668198
269 + 8667929 = 8668198

Showing the first eight; more decompositions exist.
