Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722458, here are decompositions:

11 + 8722447 = 8722458
29 + 8722429 = 8722458
67 + 8722391 = 8722458
97 + 8722361 = 8722458
127 + 8722331 = 8722458
167 + 8722291 = 8722458
271 + 8722187 = 8722458
359 + 8722099 = 8722458

Showing the first eight; more decompositions exist.
