Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680266, here are decompositions:

17 + 8680249 = 8680266
37 + 8680229 = 8680266
47 + 8680219 = 8680266
53 + 8680213 = 8680266
79 + 8680187 = 8680266
109 + 8680157 = 8680266
113 + 8680153 = 8680266
163 + 8680103 = 8680266

Showing the first eight; more decompositions exist.
