Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646522, here are decompositions:

11 + 8646511 = 8646522
19 + 8646503 = 8646522
43 + 8646479 = 8646522
193 + 8646329 = 8646522
223 + 8646299 = 8646522
229 + 8646293 = 8646522
263 + 8646259 = 8646522
359 + 8646163 = 8646522

Showing the first eight; more decompositions exist.
