Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618800, here are decompositions:

11 + 8618789 = 8618800
17 + 8618783 = 8618800
41 + 8618759 = 8618800
53 + 8618747 = 8618800
101 + 8618699 = 8618800
233 + 8618567 = 8618800
317 + 8618483 = 8618800
461 + 8618339 = 8618800

Showing the first eight; more decompositions exist.
