Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722, here are decompositions:

3 + 8719 = 8722
23 + 8699 = 8722
29 + 8693 = 8722
41 + 8681 = 8722
53 + 8669 = 8722
59 + 8663 = 8722
113 + 8609 = 8722
149 + 8573 = 8722

Showing the first eight; more decompositions exist.
