Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646270, here are decompositions:

11 + 8646259 = 8646270
13 + 8646257 = 8646270
23 + 8646247 = 8646270
37 + 8646233 = 8646270
43 + 8646227 = 8646270
47 + 8646223 = 8646270
89 + 8646181 = 8646270
107 + 8646163 = 8646270

Showing the first eight; more decompositions exist.
