Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687450, here are decompositions:

67 + 8687383 = 8687450
151 + 8687299 = 8687450
223 + 8687227 = 8687450
241 + 8687209 = 8687450
643 + 8686807 = 8687450
883 + 8686567 = 8687450
991 + 8686459 = 8687450
1153 + 8686297 = 8687450

Showing the first eight; more decompositions exist.
