Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722124, here are decompositions:

7 + 8722117 = 8722124
31 + 8722093 = 8722124
43 + 8722081 = 8722124
97 + 8722027 = 8722124
127 + 8721997 = 8722124
211 + 8721913 = 8722124
241 + 8721883 = 8722124
457 + 8721667 = 8722124

Showing the first eight; more decompositions exist.
