Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628188, here are decompositions:

7 + 8628181 = 8628188
31 + 8628157 = 8628188
67 + 8628121 = 8628188
139 + 8628049 = 8628188
157 + 8628031 = 8628188
181 + 8628007 = 8628188
211 + 8627977 = 8628188
241 + 8627947 = 8628188

Showing the first eight; more decompositions exist.
