Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722184, here are decompositions:

13 + 8722171 = 8722184
61 + 8722123 = 8722184
67 + 8722117 = 8722184
103 + 8722081 = 8722184
151 + 8722033 = 8722184
157 + 8722027 = 8722184
271 + 8721913 = 8722184
277 + 8721907 = 8722184

Showing the first eight; more decompositions exist.
