Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646488, here are decompositions:

31 + 8646457 = 8646488
127 + 8646361 = 8646488
211 + 8646277 = 8646488
229 + 8646259 = 8646488
241 + 8646247 = 8646488
307 + 8646181 = 8646488
547 + 8645941 = 8646488
601 + 8645887 = 8646488

Showing the first eight; more decompositions exist.
