Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722226, here are decompositions:

3 + 8722223 = 8722226
103 + 8722123 = 8722226
109 + 8722117 = 8722226
127 + 8722099 = 8722226
193 + 8722033 = 8722226
199 + 8722027 = 8722226
229 + 8721997 = 8722226
313 + 8721913 = 8722226

Showing the first eight; more decompositions exist.
