Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722196, here are decompositions:

3 + 8722193 = 8722196
73 + 8722123 = 8722196
79 + 8722117 = 8722196
97 + 8722099 = 8722196
103 + 8722093 = 8722196
163 + 8722033 = 8722196
199 + 8721997 = 8722196
283 + 8721913 = 8722196

Showing the first eight; more decompositions exist.
