Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611906, here are decompositions:

3 + 8611903 = 8611906
47 + 8611859 = 8611906
59 + 8611847 = 8611906
113 + 8611793 = 8611906
197 + 8611709 = 8611906
227 + 8611679 = 8611906
239 + 8611667 = 8611906
263 + 8611643 = 8611906

Showing the first eight; more decompositions exist.
