Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668266, here are decompositions:

59 + 8668207 = 8668266
73 + 8668193 = 8668266
109 + 8668157 = 8668266
193 + 8668073 = 8668266
199 + 8668067 = 8668266
223 + 8668043 = 8668266
293 + 8667973 = 8668266
317 + 8667949 = 8668266

Showing the first eight; more decompositions exist.
