Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697564, here are decompositions:

13 + 8697551 = 8697564
53 + 8697511 = 8697564
61 + 8697503 = 8697564
131 + 8697433 = 8697564
157 + 8697407 = 8697564
251 + 8697313 = 8697564
263 + 8697301 = 8697564
311 + 8697253 = 8697564

Showing the first eight; more decompositions exist.
