Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639476, here are decompositions:

17 + 8639459 = 8639476
23 + 8639453 = 8639476
113 + 8639363 = 8639476
227 + 8639249 = 8639476
257 + 8639219 = 8639476
269 + 8639207 = 8639476
353 + 8639123 = 8639476
449 + 8639027 = 8639476

Showing the first eight; more decompositions exist.
