Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722572, here are decompositions:

31 + 8722541 = 8722572
73 + 8722499 = 8722572
101 + 8722471 = 8722572
113 + 8722459 = 8722572
149 + 8722423 = 8722572
163 + 8722409 = 8722572
179 + 8722393 = 8722572
181 + 8722391 = 8722572

Showing the first eight; more decompositions exist.
