Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687628, here are decompositions:

29 + 8687599 = 8687628
41 + 8687587 = 8687628
107 + 8687521 = 8687628
149 + 8687479 = 8687628
151 + 8687477 = 8687628
167 + 8687461 = 8687628
199 + 8687429 = 8687628
227 + 8687401 = 8687628

Showing the first eight; more decompositions exist.
