Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634428, here are decompositions:

7 + 8634421 = 8634428
31 + 8634397 = 8634428
37 + 8634391 = 8634428
379 + 8634049 = 8634428
457 + 8633971 = 8634428
487 + 8633941 = 8634428
571 + 8633857 = 8634428
601 + 8633827 = 8634428

Showing the first eight; more decompositions exist.
