Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646264, here are decompositions:

5 + 8646259 = 8646264
7 + 8646257 = 8646264
17 + 8646247 = 8646264
31 + 8646233 = 8646264
37 + 8646227 = 8646264
41 + 8646223 = 8646264
43 + 8646221 = 8646264
83 + 8646181 = 8646264

Showing the first eight; more decompositions exist.
