Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647268, here are decompositions:

37 + 8647231 = 8647268
139 + 8647129 = 8647268
241 + 8647027 = 8647268
307 + 8646961 = 8647268
379 + 8646889 = 8647268
547 + 8646721 = 8647268
601 + 8646667 = 8647268
661 + 8646607 = 8647268

Showing the first eight; more decompositions exist.
