Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641358, here are decompositions:

7 + 8641351 = 8641358
31 + 8641327 = 8641358
109 + 8641249 = 8641358
127 + 8641231 = 8641358
211 + 8641147 = 8641358
409 + 8640949 = 8641358
487 + 8640871 = 8641358
499 + 8640859 = 8641358

Showing the first eight; more decompositions exist.
