Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628210, here are decompositions:

7 + 8628203 = 8628210
23 + 8628187 = 8628210
29 + 8628181 = 8628210
37 + 8628173 = 8628210
53 + 8628157 = 8628210
61 + 8628149 = 8628210
79 + 8628131 = 8628210
89 + 8628121 = 8628210

Showing the first eight; more decompositions exist.
