Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668136, here are decompositions:

3 + 8668133 = 8668136
73 + 8668063 = 8668136
79 + 8668057 = 8668136
157 + 8667979 = 8668136
163 + 8667973 = 8668136
223 + 8667913 = 8668136
229 + 8667907 = 8668136
307 + 8667829 = 8668136

Showing the first eight; more decompositions exist.
