Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688564, here are decompositions:

7 + 8688557 = 8688564
11 + 8688553 = 8688564
13 + 8688551 = 8688564
37 + 8688527 = 8688564
43 + 8688521 = 8688564
67 + 8688497 = 8688564
127 + 8688437 = 8688564
167 + 8688397 = 8688564

Showing the first eight; more decompositions exist.
