Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646424, here are decompositions:

23 + 8646401 = 8646424
47 + 8646377 = 8646424
107 + 8646317 = 8646424
131 + 8646293 = 8646424
167 + 8646257 = 8646424
191 + 8646233 = 8646424
197 + 8646227 = 8646424
317 + 8646107 = 8646424

Showing the first eight; more decompositions exist.
