Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628230, here are decompositions:

43 + 8628187 = 8628230
73 + 8628157 = 8628230
109 + 8628121 = 8628230
181 + 8628049 = 8628230
199 + 8628031 = 8628230
211 + 8628019 = 8628230
223 + 8628007 = 8628230
277 + 8627953 = 8628230

Showing the first eight; more decompositions exist.
