Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687498, here are decompositions:

19 + 8687479 = 8687498
31 + 8687467 = 8687498
37 + 8687461 = 8687498
97 + 8687401 = 8687498
139 + 8687359 = 8687498
181 + 8687317 = 8687498
199 + 8687299 = 8687498
271 + 8687227 = 8687498

Showing the first eight; more decompositions exist.
