Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631584, here are decompositions:

67 + 8631517 = 8631584
193 + 8631391 = 8631584
211 + 8631373 = 8631584
277 + 8631307 = 8631584
307 + 8631277 = 8631584
337 + 8631247 = 8631584
433 + 8631151 = 8631584
487 + 8631097 = 8631584

Showing the first eight; more decompositions exist.
