Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687528, here are decompositions:

7 + 8687521 = 8687528
61 + 8687467 = 8687528
67 + 8687461 = 8687528
127 + 8687401 = 8687528
211 + 8687317 = 8687528
229 + 8687299 = 8687528
331 + 8687197 = 8687528
379 + 8687149 = 8687528

Showing the first eight; more decompositions exist.
