Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639524, here are decompositions:

17 + 8639507 = 8639524
71 + 8639453 = 8639524
83 + 8639441 = 8639524
233 + 8639291 = 8639524
251 + 8639273 = 8639524
263 + 8639261 = 8639524
317 + 8639207 = 8639524
347 + 8639177 = 8639524

Showing the first eight; more decompositions exist.
