Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722768, here are decompositions:

11 + 8722757 = 8722768
29 + 8722739 = 8722768
107 + 8722661 = 8722768
137 + 8722631 = 8722768
227 + 8722541 = 8722768
251 + 8722517 = 8722768
269 + 8722499 = 8722768
359 + 8722409 = 8722768

Showing the first eight; more decompositions exist.
