Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611888, here are decompositions:

29 + 8611859 = 8611888
41 + 8611847 = 8611888
59 + 8611829 = 8611888
167 + 8611721 = 8611888
179 + 8611709 = 8611888
191 + 8611697 = 8611888
269 + 8611619 = 8611888
359 + 8611529 = 8611888

Showing the first eight; more decompositions exist.
