Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684650, here are decompositions:

53 + 8684597 = 8684650
113 + 8684537 = 8684650
137 + 8684513 = 8684650
167 + 8684483 = 8684650
179 + 8684471 = 8684650
239 + 8684411 = 8684650
383 + 8684267 = 8684650
389 + 8684261 = 8684650

Showing the first eight; more decompositions exist.
