Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687568, here are decompositions:

47 + 8687521 = 8687568
89 + 8687479 = 8687568
101 + 8687467 = 8687568
107 + 8687461 = 8687568
139 + 8687429 = 8687568
167 + 8687401 = 8687568
181 + 8687387 = 8687568
199 + 8687369 = 8687568

Showing the first eight; more decompositions exist.
