Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605904, here are decompositions:

31 + 8605873 = 8605904
61 + 8605843 = 8605904
103 + 8605801 = 8605904
337 + 8605567 = 8605904
457 + 8605447 = 8605904
607 + 8605297 = 8605904
631 + 8605273 = 8605904
673 + 8605231 = 8605904

Showing the first eight; more decompositions exist.
