Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623210, here are decompositions:

17 + 8623193 = 8623210
107 + 8623103 = 8623210
137 + 8623073 = 8623210
149 + 8623061 = 8623210
173 + 8623037 = 8623210
179 + 8623031 = 8623210
191 + 8623019 = 8623210
227 + 8622983 = 8623210

Showing the first eight; more decompositions exist.
