Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722876, here are decompositions:

17 + 8722859 = 8722876
47 + 8722829 = 8722876
137 + 8722739 = 8722876
233 + 8722643 = 8722876
263 + 8722613 = 8722876
269 + 8722607 = 8722876
359 + 8722517 = 8722876
467 + 8722409 = 8722876

Showing the first eight; more decompositions exist.
