Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687630, here are decompositions:

31 + 8687599 = 8687630
43 + 8687587 = 8687630
109 + 8687521 = 8687630
151 + 8687479 = 8687630
163 + 8687467 = 8687630
229 + 8687401 = 8687630
271 + 8687359 = 8687630
313 + 8687317 = 8687630

Showing the first eight; more decompositions exist.
