Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715800, here are decompositions:

7 + 8715793 = 8715800
13 + 8715787 = 8715800
31 + 8715769 = 8715800
97 + 8715703 = 8715800
103 + 8715697 = 8715800
127 + 8715673 = 8715800
151 + 8715649 = 8715800
199 + 8715601 = 8715800

Showing the first eight; more decompositions exist.
