Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605646, here are decompositions:

37 + 8605609 = 8605646
79 + 8605567 = 8605646
103 + 8605543 = 8605646
199 + 8605447 = 8605646
277 + 8605369 = 8605646
349 + 8605297 = 8605646
373 + 8605273 = 8605646
409 + 8605237 = 8605646

Showing the first eight; more decompositions exist.
