Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722574, here are decompositions:

97 + 8722477 = 8722574
103 + 8722471 = 8722574
127 + 8722447 = 8722574
151 + 8722423 = 8722574
181 + 8722393 = 8722574
241 + 8722333 = 8722574
271 + 8722303 = 8722574
277 + 8722297 = 8722574

Showing the first eight; more decompositions exist.
