Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611968, here are decompositions:

7 + 8611961 = 8611968
89 + 8611879 = 8611968
109 + 8611859 = 8611968
139 + 8611829 = 8611968
149 + 8611819 = 8611968
179 + 8611789 = 8611968
271 + 8611697 = 8611968
349 + 8611619 = 8611968

Showing the first eight; more decompositions exist.
