Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611944, here are decompositions:

41 + 8611903 = 8611944
53 + 8611891 = 8611944
71 + 8611873 = 8611944
97 + 8611847 = 8611944
151 + 8611793 = 8611944
223 + 8611721 = 8611944
241 + 8611703 = 8611944
277 + 8611667 = 8611944

Showing the first eight; more decompositions exist.
