Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722256, here are decompositions:

19 + 8722237 = 8722256
139 + 8722117 = 8722256
157 + 8722099 = 8722256
163 + 8722093 = 8722256
223 + 8722033 = 8722256
229 + 8722027 = 8722256
349 + 8721907 = 8722256
373 + 8721883 = 8722256

Showing the first eight; more decompositions exist.
