Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722956, here are decompositions:

7 + 8722949 = 8722956
43 + 8722913 = 8722956
79 + 8722877 = 8722956
97 + 8722859 = 8722956
127 + 8722829 = 8722956
157 + 8722799 = 8722956
167 + 8722789 = 8722956
199 + 8722757 = 8722956

Showing the first eight; more decompositions exist.
