Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612188, here are decompositions:

89 + 8612099 = 8612188
131 + 8612057 = 8612188
149 + 8612039 = 8612188
197 + 8611991 = 8612188
227 + 8611961 = 8612188
359 + 8611829 = 8612188
467 + 8611721 = 8612188
479 + 8611709 = 8612188

Showing the first eight; more decompositions exist.
