Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722268, here are decompositions:

31 + 8722237 = 8722268
97 + 8722171 = 8722268
151 + 8722117 = 8722268
241 + 8722027 = 8722268
271 + 8721997 = 8722268
601 + 8721667 = 8722268
661 + 8721607 = 8722268
727 + 8721541 = 8722268

Showing the first eight; more decompositions exist.
