Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722116, here are decompositions:

17 + 8722099 = 8722116
19 + 8722097 = 8722116
23 + 8722093 = 8722116
37 + 8722079 = 8722116
83 + 8722033 = 8722116
89 + 8722027 = 8722116
97 + 8722019 = 8722116
107 + 8722009 = 8722116

Showing the first eight; more decompositions exist.
