Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647266, here are decompositions:

13 + 8647253 = 8647266
37 + 8647229 = 8647266
73 + 8647193 = 8647266
83 + 8647183 = 8647266
109 + 8647157 = 8647266
127 + 8647139 = 8647266
137 + 8647129 = 8647266
139 + 8647127 = 8647266

Showing the first eight; more decompositions exist.
