Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722460, here are decompositions:

13 + 8722447 = 8722460
31 + 8722429 = 8722460
37 + 8722423 = 8722460
67 + 8722393 = 8722460
127 + 8722333 = 8722460
157 + 8722303 = 8722460
163 + 8722297 = 8722460
223 + 8722237 = 8722460

Showing the first eight; more decompositions exist.
