Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644266, here are decompositions:

5 + 8644261 = 8644266
13 + 8644253 = 8644266
23 + 8644243 = 8644266
53 + 8644213 = 8644266
79 + 8644187 = 8644266
109 + 8644157 = 8644266
269 + 8643997 = 8644266
307 + 8643959 = 8644266

Showing the first eight; more decompositions exist.
