Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8599872, here are decompositions:

5 + 8599867 = 8599872
23 + 8599849 = 8599872
53 + 8599819 = 8599872
79 + 8599793 = 8599872
101 + 8599771 = 8599872
179 + 8599693 = 8599872
181 + 8599691 = 8599872
199 + 8599673 = 8599872

Showing the first eight; more decompositions exist.
