Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722476, here are decompositions:

5 + 8722471 = 8722476
17 + 8722459 = 8722476
29 + 8722447 = 8722476
47 + 8722429 = 8722476
53 + 8722423 = 8722476
67 + 8722409 = 8722476
83 + 8722393 = 8722476
109 + 8722367 = 8722476

Showing the first eight; more decompositions exist.
