Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687566, here are decompositions:

53 + 8687513 = 8687566
89 + 8687477 = 8687566
113 + 8687453 = 8687566
137 + 8687429 = 8687566
179 + 8687387 = 8687566
197 + 8687369 = 8687566
257 + 8687309 = 8687566
263 + 8687303 = 8687566

Showing the first eight; more decompositions exist.
