Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611966, here are decompositions:

5 + 8611961 = 8611966
107 + 8611859 = 8611966
137 + 8611829 = 8611966
173 + 8611793 = 8611966
257 + 8611709 = 8611966
263 + 8611703 = 8611966
269 + 8611697 = 8611966
347 + 8611619 = 8611966

Showing the first eight; more decompositions exist.
