Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722960, here are decompositions:

11 + 8722949 = 8722960
47 + 8722913 = 8722960
83 + 8722877 = 8722960
101 + 8722859 = 8722960
131 + 8722829 = 8722960
317 + 8722643 = 8722960
347 + 8722613 = 8722960
353 + 8722607 = 8722960

Showing the first eight; more decompositions exist.
