Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684620, here are decompositions:

23 + 8684597 = 8684620
47 + 8684573 = 8684620
83 + 8684537 = 8684620
107 + 8684513 = 8684620
137 + 8684483 = 8684620
149 + 8684471 = 8684620
353 + 8684267 = 8684620
359 + 8684261 = 8684620

Showing the first eight; more decompositions exist.
