Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691264, here are decompositions:

13 + 8691251 = 8691264
17 + 8691247 = 8691264
41 + 8691223 = 8691264
53 + 8691211 = 8691264
97 + 8691167 = 8691264
107 + 8691157 = 8691264
137 + 8691127 = 8691264
163 + 8691101 = 8691264

Showing the first eight; more decompositions exist.
