Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687508, here are decompositions:

29 + 8687479 = 8687508
31 + 8687477 = 8687508
41 + 8687467 = 8687508
47 + 8687461 = 8687508
79 + 8687429 = 8687508
107 + 8687401 = 8687508
127 + 8687381 = 8687508
139 + 8687369 = 8687508

Showing the first eight; more decompositions exist.
