Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668686, here are decompositions:

43 + 8668643 = 8668686
73 + 8668613 = 8668686
109 + 8668577 = 8668686
137 + 8668549 = 8668686
139 + 8668547 = 8668686
163 + 8668523 = 8668686
167 + 8668519 = 8668686
197 + 8668489 = 8668686

Showing the first eight; more decompositions exist.
