Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8721096, here are decompositions:

17 + 8721079 = 8721096
19 + 8721077 = 8721096
47 + 8721049 = 8721096
53 + 8721043 = 8721096
67 + 8721029 = 8721096
127 + 8720969 = 8721096
149 + 8720947 = 8721096
257 + 8720839 = 8721096

Showing the first eight; more decompositions exist.
