Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687504, here are decompositions:

37 + 8687467 = 8687504
43 + 8687461 = 8687504
103 + 8687401 = 8687504
271 + 8687233 = 8687504
277 + 8687227 = 8687504
307 + 8687197 = 8687504
373 + 8687131 = 8687504
523 + 8686981 = 8687504

Showing the first eight; more decompositions exist.
