Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722834, here are decompositions:

5 + 8722829 = 8722834
173 + 8722661 = 8722834
191 + 8722643 = 8722834
227 + 8722607 = 8722834
293 + 8722541 = 8722834
317 + 8722517 = 8722834
443 + 8722391 = 8722834
467 + 8722367 = 8722834

Showing the first eight; more decompositions exist.
