Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647248, here are decompositions:

17 + 8647231 = 8647248
19 + 8647229 = 8647248
67 + 8647181 = 8647248
109 + 8647139 = 8647248
157 + 8647091 = 8647248
227 + 8647021 = 8647248
241 + 8647007 = 8647248
277 + 8646971 = 8647248

Showing the first eight; more decompositions exist.
