Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605436, here are decompositions:

3 + 8605433 = 8605436
67 + 8605369 = 8605436
139 + 8605297 = 8605436
163 + 8605273 = 8605436
199 + 8605237 = 8605436
277 + 8605159 = 8605436
283 + 8605153 = 8605436
379 + 8605057 = 8605436

Showing the first eight; more decompositions exist.
