Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670, here are decompositions:

7 + 8663 = 8670
23 + 8647 = 8670
29 + 8641 = 8670
41 + 8629 = 8670
43 + 8627 = 8670
47 + 8623 = 8670
61 + 8609 = 8670
71 + 8599 = 8670

Showing the first eight; more decompositions exist.
