Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8653722, here are decompositions:

5 + 8653717 = 8653722
13 + 8653709 = 8653722
19 + 8653703 = 8653722
23 + 8653699 = 8653722
31 + 8653691 = 8653722
43 + 8653679 = 8653722
53 + 8653669 = 8653722
71 + 8653651 = 8653722

Showing the first eight; more decompositions exist.
