Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719800, here are decompositions:

29 + 8719771 = 8719800
53 + 8719747 = 8719800
97 + 8719703 = 8719800
101 + 8719699 = 8719800
137 + 8719663 = 8719800
139 + 8719661 = 8719800
197 + 8719603 = 8719800
223 + 8719577 = 8719800

Showing the first eight; more decompositions exist.
