Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616564, here are decompositions:

17 + 8616547 = 8616564
23 + 8616541 = 8616564
31 + 8616533 = 8616564
37 + 8616527 = 8616564
71 + 8616493 = 8616564
107 + 8616457 = 8616564
157 + 8616407 = 8616564
167 + 8616397 = 8616564

Showing the first eight; more decompositions exist.
