Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605340, here are decompositions:

43 + 8605297 = 8605340
67 + 8605273 = 8605340
103 + 8605237 = 8605340
109 + 8605231 = 8605340
181 + 8605159 = 8605340
193 + 8605147 = 8605340
283 + 8605057 = 8605340
349 + 8604991 = 8605340

Showing the first eight; more decompositions exist.
