Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687876, here are decompositions:

3 + 8687873 = 8687876
79 + 8687797 = 8687876
163 + 8687713 = 8687876
277 + 8687599 = 8687876
397 + 8687479 = 8687876
409 + 8687467 = 8687876
577 + 8687299 = 8687876
643 + 8687233 = 8687876

Showing the first eight; more decompositions exist.
