Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722530, here are decompositions:

13 + 8722517 = 8722530
31 + 8722499 = 8722530
53 + 8722477 = 8722530
59 + 8722471 = 8722530
71 + 8722459 = 8722530
83 + 8722447 = 8722530
101 + 8722429 = 8722530
107 + 8722423 = 8722530

Showing the first eight; more decompositions exist.
