Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687582, here are decompositions:

61 + 8687521 = 8687582
103 + 8687479 = 8687582
181 + 8687401 = 8687582
199 + 8687383 = 8687582
223 + 8687359 = 8687582
283 + 8687299 = 8687582
349 + 8687233 = 8687582
373 + 8687209 = 8687582

Showing the first eight; more decompositions exist.
