Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649584, here are decompositions:

3 + 8649581 = 8649584
67 + 8649517 = 8649584
193 + 8649391 = 8649584
241 + 8649343 = 8649584
331 + 8649253 = 8649584
373 + 8649211 = 8649584
397 + 8649187 = 8649584
523 + 8649061 = 8649584

Showing the first eight; more decompositions exist.
