Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722524, here are decompositions:

7 + 8722517 = 8722524
47 + 8722477 = 8722524
53 + 8722471 = 8722524
101 + 8722423 = 8722524
131 + 8722393 = 8722524
157 + 8722367 = 8722524
163 + 8722361 = 8722524
191 + 8722333 = 8722524

Showing the first eight; more decompositions exist.
