Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646266, here are decompositions:

7 + 8646259 = 8646266
19 + 8646247 = 8646266
43 + 8646223 = 8646266
103 + 8646163 = 8646266
163 + 8646103 = 8646266
367 + 8645899 = 8646266
379 + 8645887 = 8646266
463 + 8645803 = 8646266

Showing the first eight; more decompositions exist.
