Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669208, here are decompositions:

19 + 8669189 = 8669208
29 + 8669179 = 8669208
101 + 8669107 = 8669208
137 + 8669071 = 8669208
167 + 8669041 = 8669208
181 + 8669027 = 8669208
241 + 8668967 = 8669208
257 + 8668951 = 8669208

Showing the first eight; more decompositions exist.
