Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722906, here are decompositions:

29 + 8722877 = 8722906
47 + 8722859 = 8722906
107 + 8722799 = 8722906
149 + 8722757 = 8722906
167 + 8722739 = 8722906
233 + 8722673 = 8722906
263 + 8722643 = 8722906
293 + 8722613 = 8722906

Showing the first eight; more decompositions exist.
