Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722722, here are decompositions:

11 + 8722711 = 8722722
61 + 8722661 = 8722722
79 + 8722643 = 8722722
101 + 8722621 = 8722722
109 + 8722613 = 8722722
181 + 8722541 = 8722722
223 + 8722499 = 8722722
251 + 8722471 = 8722722

Showing the first eight; more decompositions exist.
