Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641674, here are decompositions:

5 + 8641669 = 8641674
23 + 8641651 = 8641674
31 + 8641643 = 8641674
43 + 8641631 = 8641674
53 + 8641621 = 8641674
61 + 8641613 = 8641674
71 + 8641603 = 8641674
103 + 8641571 = 8641674

Showing the first eight; more decompositions exist.
