Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605266, here are decompositions:

29 + 8605237 = 8605266
37 + 8605229 = 8605266
79 + 8605187 = 8605266
97 + 8605169 = 8605266
107 + 8605159 = 8605266
113 + 8605153 = 8605266
283 + 8604983 = 8605266
353 + 8604913 = 8605266

Showing the first eight; more decompositions exist.
