Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691408, here are decompositions:

17 + 8691391 = 8691408
41 + 8691367 = 8691408
109 + 8691299 = 8691408
127 + 8691281 = 8691408
139 + 8691269 = 8691408
157 + 8691251 = 8691408
179 + 8691229 = 8691408
197 + 8691211 = 8691408

Showing the first eight; more decompositions exist.
