Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687476, here are decompositions:

23 + 8687453 = 8687476
47 + 8687429 = 8687476
53 + 8687423 = 8687476
89 + 8687387 = 8687476
107 + 8687369 = 8687476
113 + 8687363 = 8687476
167 + 8687309 = 8687476
173 + 8687303 = 8687476

Showing the first eight; more decompositions exist.
