Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722552, here are decompositions:

11 + 8722541 = 8722552
53 + 8722499 = 8722552
191 + 8722361 = 8722552
269 + 8722283 = 8722552
359 + 8722193 = 8722552
383 + 8722169 = 8722552
563 + 8721989 = 8722552
701 + 8721851 = 8722552

Showing the first eight; more decompositions exist.
