Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697440, here are decompositions:

7 + 8697433 = 8697440
61 + 8697379 = 8697440
97 + 8697343 = 8697440
127 + 8697313 = 8697440
139 + 8697301 = 8697440
163 + 8697277 = 8697440
277 + 8697163 = 8697440
307 + 8697133 = 8697440

Showing the first eight; more decompositions exist.
