Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646420, here are decompositions:

17 + 8646403 = 8646420
19 + 8646401 = 8646420
31 + 8646389 = 8646420
43 + 8646377 = 8646420
59 + 8646361 = 8646420
103 + 8646317 = 8646420
127 + 8646293 = 8646420
151 + 8646269 = 8646420

Showing the first eight; more decompositions exist.
