Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691360, here are decompositions:

47 + 8691313 = 8691360
61 + 8691299 = 8691360
79 + 8691281 = 8691360
109 + 8691251 = 8691360
113 + 8691247 = 8691360
131 + 8691229 = 8691360
137 + 8691223 = 8691360
149 + 8691211 = 8691360

Showing the first eight; more decompositions exist.
