Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726800, here are decompositions:

11 + 8726789 = 8726800
23 + 8726777 = 8726800
41 + 8726759 = 8726800
101 + 8726699 = 8726800
113 + 8726687 = 8726800
167 + 8726633 = 8726800
227 + 8726573 = 8726800
293 + 8726507 = 8726800

Showing the first eight; more decompositions exist.
