Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641722, here are decompositions:

13 + 8641709 = 8641722
53 + 8641669 = 8641722
71 + 8641651 = 8641722
79 + 8641643 = 8641722
101 + 8641621 = 8641722
109 + 8641613 = 8641722
151 + 8641571 = 8641722
179 + 8641543 = 8641722

Showing the first eight; more decompositions exist.
