Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8599920, here are decompositions:

23 + 8599897 = 8599920
29 + 8599891 = 8599920
53 + 8599867 = 8599920
71 + 8599849 = 8599920
97 + 8599823 = 8599920
101 + 8599819 = 8599920
103 + 8599817 = 8599920
127 + 8599793 = 8599920

Showing the first eight; more decompositions exist.
