Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722502, here are decompositions:

3 + 8722499 = 8722502
31 + 8722471 = 8722502
43 + 8722459 = 8722502
73 + 8722429 = 8722502
79 + 8722423 = 8722502
109 + 8722393 = 8722502
163 + 8722339 = 8722502
199 + 8722303 = 8722502

Showing the first eight; more decompositions exist.
