Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722528, here are decompositions:

11 + 8722517 = 8722528
29 + 8722499 = 8722528
137 + 8722391 = 8722528
167 + 8722361 = 8722528
197 + 8722331 = 8722528
317 + 8722211 = 8722528
359 + 8722169 = 8722528
431 + 8722097 = 8722528

Showing the first eight; more decompositions exist.
