Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628222, here are decompositions:

19 + 8628203 = 8628222
41 + 8628181 = 8628222
61 + 8628161 = 8628222
73 + 8628149 = 8628222
101 + 8628121 = 8628222
173 + 8628049 = 8628222
191 + 8628031 = 8628222
269 + 8627953 = 8628222

Showing the first eight; more decompositions exist.
