Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628194, here are decompositions:

7 + 8628187 = 8628194
13 + 8628181 = 8628194
37 + 8628157 = 8628194
73 + 8628121 = 8628194
97 + 8628097 = 8628194
163 + 8628031 = 8628194
241 + 8627953 = 8628194
283 + 8627911 = 8628194

Showing the first eight; more decompositions exist.
