Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620266, here are decompositions:

7 + 8620259 = 8620266
47 + 8620219 = 8620266
79 + 8620187 = 8620266
107 + 8620159 = 8620266
157 + 8620109 = 8620266
197 + 8620069 = 8620266
223 + 8620043 = 8620266
269 + 8619997 = 8620266

Showing the first eight; more decompositions exist.
