Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718458, here are decompositions:

19 + 8718439 = 8718458
31 + 8718427 = 8718458
109 + 8718349 = 8718458
157 + 8718301 = 8718458
181 + 8718277 = 8718458
211 + 8718247 = 8718458
241 + 8718217 = 8718458
349 + 8718109 = 8718458

Showing the first eight; more decompositions exist.
