Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669210, here are decompositions:

3 + 8669207 = 8669210
31 + 8669179 = 8669210
97 + 8669113 = 8669210
103 + 8669107 = 8669210
127 + 8669083 = 8669210
139 + 8669071 = 8669210
313 + 8668897 = 8669210
337 + 8668873 = 8669210

Showing the first eight; more decompositions exist.
