Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684784, here are decompositions:

13 + 8684771 = 8684784
23 + 8684761 = 8684784
37 + 8684747 = 8684784
71 + 8684713 = 8684784
127 + 8684657 = 8684784
197 + 8684587 = 8684784
211 + 8684573 = 8684784
263 + 8684521 = 8684784

Showing the first eight; more decompositions exist.
