Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647118, here are decompositions:

97 + 8647021 = 8647118
157 + 8646961 = 8647118
229 + 8646889 = 8647118
367 + 8646751 = 8647118
397 + 8646721 = 8647118
409 + 8646709 = 8647118
547 + 8646571 = 8647118
607 + 8646511 = 8647118

Showing the first eight; more decompositions exist.
