Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687558, here are decompositions:

37 + 8687521 = 8687558
79 + 8687479 = 8687558
97 + 8687461 = 8687558
157 + 8687401 = 8687558
199 + 8687359 = 8687558
241 + 8687317 = 8687558
331 + 8687227 = 8687558
349 + 8687209 = 8687558

Showing the first eight; more decompositions exist.
