Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669164, here are decompositions:

5 + 8669159 = 8669164
41 + 8669123 = 8669164
47 + 8669117 = 8669164
137 + 8669027 = 8669164
191 + 8668973 = 8669164
197 + 8668967 = 8669164
263 + 8668901 = 8669164
347 + 8668817 = 8669164

Showing the first eight; more decompositions exist.
