Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687584, here are decompositions:

71 + 8687513 = 8687584
107 + 8687477 = 8687584
131 + 8687453 = 8687584
197 + 8687387 = 8687584
263 + 8687321 = 8687584
281 + 8687303 = 8687584
293 + 8687291 = 8687584
401 + 8687183 = 8687584

Showing the first eight; more decompositions exist.
