Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647424, here are decompositions:

7 + 8647417 = 8647424
13 + 8647411 = 8647424
31 + 8647393 = 8647424
151 + 8647273 = 8647424
193 + 8647231 = 8647424
241 + 8647183 = 8647424
397 + 8647027 = 8647424
463 + 8646961 = 8647424

Showing the first eight; more decompositions exist.
