Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668306, here are decompositions:

5 + 8668301 = 8668306
113 + 8668193 = 8668306
149 + 8668157 = 8668306
173 + 8668133 = 8668306
233 + 8668073 = 8668306
239 + 8668067 = 8668306
263 + 8668043 = 8668306
443 + 8667863 = 8668306

Showing the first eight; more decompositions exist.
