Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722632, here are decompositions:

11 + 8722621 = 8722632
19 + 8722613 = 8722632
29 + 8722603 = 8722632
173 + 8722459 = 8722632
223 + 8722409 = 8722632
239 + 8722393 = 8722632
241 + 8722391 = 8722632
271 + 8722361 = 8722632

Showing the first eight; more decompositions exist.
