Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722500, here are decompositions:

23 + 8722477 = 8722500
29 + 8722471 = 8722500
41 + 8722459 = 8722500
53 + 8722447 = 8722500
71 + 8722429 = 8722500
107 + 8722393 = 8722500
109 + 8722391 = 8722500
139 + 8722361 = 8722500

Showing the first eight; more decompositions exist.
