Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722992, here are decompositions:

11 + 8722981 = 8722992
23 + 8722969 = 8722992
43 + 8722949 = 8722992
79 + 8722913 = 8722992
101 + 8722891 = 8722992
151 + 8722841 = 8722992
163 + 8722829 = 8722992
193 + 8722799 = 8722992

Showing the first eight; more decompositions exist.
