Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645462, here are decompositions:

13 + 8645449 = 8645462
19 + 8645443 = 8645462
31 + 8645431 = 8645462
103 + 8645359 = 8645462
109 + 8645353 = 8645462
181 + 8645281 = 8645462
193 + 8645269 = 8645462
223 + 8645239 = 8645462

Showing the first eight; more decompositions exist.
