Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687650, here are decompositions:

47 + 8687603 = 8687650
137 + 8687513 = 8687650
173 + 8687477 = 8687650
197 + 8687453 = 8687650
227 + 8687423 = 8687650
263 + 8687387 = 8687650
269 + 8687381 = 8687650
281 + 8687369 = 8687650

Showing the first eight; more decompositions exist.
