Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605400, here are decompositions:

31 + 8605369 = 8605400
103 + 8605297 = 8605400
127 + 8605273 = 8605400
163 + 8605237 = 8605400
229 + 8605171 = 8605400
241 + 8605159 = 8605400
409 + 8604991 = 8605400
439 + 8604961 = 8605400

Showing the first eight; more decompositions exist.
