Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722366, here are decompositions:

5 + 8722361 = 8722366
83 + 8722283 = 8722366
173 + 8722193 = 8722366
179 + 8722187 = 8722366
197 + 8722169 = 8722366
269 + 8722097 = 8722366
347 + 8722019 = 8722366
449 + 8721917 = 8722366

Showing the first eight; more decompositions exist.
