Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722566, here are decompositions:

67 + 8722499 = 8722566
89 + 8722477 = 8722566
107 + 8722459 = 8722566
137 + 8722429 = 8722566
157 + 8722409 = 8722566
173 + 8722393 = 8722566
199 + 8722367 = 8722566
227 + 8722339 = 8722566

Showing the first eight; more decompositions exist.
