Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722234, here are decompositions:

11 + 8722223 = 8722234
23 + 8722211 = 8722234
41 + 8722193 = 8722234
47 + 8722187 = 8722234
137 + 8722097 = 8722234
233 + 8722001 = 8722234
293 + 8721941 = 8722234
317 + 8721917 = 8722234

Showing the first eight; more decompositions exist.
