Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641716, here are decompositions:

7 + 8641709 = 8641716
19 + 8641697 = 8641716
43 + 8641673 = 8641716
47 + 8641669 = 8641716
73 + 8641643 = 8641716
103 + 8641613 = 8641716
113 + 8641603 = 8641716
173 + 8641543 = 8641716

Showing the first eight; more decompositions exist.
