Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668206, here are decompositions:

5 + 8668201 = 8668206
13 + 8668193 = 8668206
73 + 8668133 = 8668206
139 + 8668067 = 8668206
149 + 8668057 = 8668206
163 + 8668043 = 8668206
227 + 8667979 = 8668206
233 + 8667973 = 8668206

Showing the first eight; more decompositions exist.
