Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647184, here are decompositions:

3 + 8647181 = 8647184
61 + 8647123 = 8647184
157 + 8647027 = 8647184
163 + 8647021 = 8647184
223 + 8646961 = 8647184
241 + 8646943 = 8647184
331 + 8646853 = 8647184
367 + 8646817 = 8647184

Showing the first eight; more decompositions exist.
