Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687550, here are decompositions:

29 + 8687521 = 8687550
37 + 8687513 = 8687550
71 + 8687479 = 8687550
73 + 8687477 = 8687550
83 + 8687467 = 8687550
89 + 8687461 = 8687550
97 + 8687453 = 8687550
127 + 8687423 = 8687550

Showing the first eight; more decompositions exist.
