Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678800, here are decompositions:

17 + 8678783 = 8678800
23 + 8678777 = 8678800
41 + 8678759 = 8678800
47 + 8678753 = 8678800
59 + 8678741 = 8678800
101 + 8678699 = 8678800
107 + 8678693 = 8678800
131 + 8678669 = 8678800

Showing the first eight; more decompositions exist.
