Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670458, here are decompositions:

7 + 8670451 = 8670458
61 + 8670397 = 8670458
127 + 8670331 = 8670458
157 + 8670301 = 8670458
331 + 8670127 = 8670458
421 + 8670037 = 8670458
547 + 8669911 = 8670458
691 + 8669767 = 8670458

Showing the first eight; more decompositions exist.
