Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611188, here are decompositions:

7 + 8611181 = 8611188
37 + 8611151 = 8611188
41 + 8611147 = 8611188
71 + 8611117 = 8611188
151 + 8611037 = 8611188
191 + 8610997 = 8611188
227 + 8610961 = 8611188
251 + 8610937 = 8611188

Showing the first eight; more decompositions exist.
