Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646418, here are decompositions:

17 + 8646401 = 8646418
29 + 8646389 = 8646418
41 + 8646377 = 8646418
89 + 8646329 = 8646418
101 + 8646317 = 8646418
149 + 8646269 = 8646418
191 + 8646227 = 8646418
197 + 8646221 = 8646418

Showing the first eight; more decompositions exist.
