Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684564, here are decompositions:

43 + 8684521 = 8684564
61 + 8684503 = 8684564
103 + 8684461 = 8684564
127 + 8684437 = 8684564
157 + 8684407 = 8684564
223 + 8684341 = 8684564
307 + 8684257 = 8684564
433 + 8684131 = 8684564

Showing the first eight; more decompositions exist.
