Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722496, here are decompositions:

19 + 8722477 = 8722496
37 + 8722459 = 8722496
67 + 8722429 = 8722496
73 + 8722423 = 8722496
103 + 8722393 = 8722496
157 + 8722339 = 8722496
163 + 8722333 = 8722496
193 + 8722303 = 8722496

Showing the first eight; more decompositions exist.
