Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687924, here are decompositions:

13 + 8687911 = 8687924
43 + 8687881 = 8687924
97 + 8687827 = 8687924
127 + 8687797 = 8687924
211 + 8687713 = 8687924
283 + 8687641 = 8687924
337 + 8687587 = 8687924
457 + 8687467 = 8687924

Showing the first eight; more decompositions exist.
