Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722800, here are decompositions:

11 + 8722789 = 8722800
43 + 8722757 = 8722800
61 + 8722739 = 8722800
89 + 8722711 = 8722800
127 + 8722673 = 8722800
139 + 8722661 = 8722800
157 + 8722643 = 8722800
179 + 8722621 = 8722800

Showing the first eight; more decompositions exist.
