Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687516, here are decompositions:

3 + 8687513 = 8687516
37 + 8687479 = 8687516
157 + 8687359 = 8687516
199 + 8687317 = 8687516
283 + 8687233 = 8687516
307 + 8687209 = 8687516
367 + 8687149 = 8687516
709 + 8686807 = 8687516

Showing the first eight; more decompositions exist.
