Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722168, here are decompositions:

71 + 8722097 = 8722168
89 + 8722079 = 8722168
149 + 8722019 = 8722168
167 + 8722001 = 8722168
179 + 8721989 = 8722168
227 + 8721941 = 8722168
239 + 8721929 = 8722168
251 + 8721917 = 8722168

Showing the first eight; more decompositions exist.
