Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722832, here are decompositions:

3 + 8722829 = 8722832
43 + 8722789 = 8722832
211 + 8722621 = 8722832
229 + 8722603 = 8722832
373 + 8722459 = 8722832
409 + 8722423 = 8722832
439 + 8722393 = 8722832
499 + 8722333 = 8722832

Showing the first eight; more decompositions exist.
