Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687804, here are decompositions:

7 + 8687797 = 8687804
163 + 8687641 = 8687804
283 + 8687521 = 8687804
337 + 8687467 = 8687804
421 + 8687383 = 8687804
487 + 8687317 = 8687804
571 + 8687233 = 8687804
577 + 8687227 = 8687804

Showing the first eight; more decompositions exist.
