Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722542, here are decompositions:

43 + 8722499 = 8722542
71 + 8722471 = 8722542
83 + 8722459 = 8722542
113 + 8722429 = 8722542
149 + 8722393 = 8722542
151 + 8722391 = 8722542
181 + 8722361 = 8722542
211 + 8722331 = 8722542

Showing the first eight; more decompositions exist.
