Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722086, here are decompositions:

5 + 8722081 = 8722086
7 + 8722079 = 8722086
53 + 8722033 = 8722086
59 + 8722027 = 8722086
67 + 8722019 = 8722086
89 + 8721997 = 8722086
97 + 8721989 = 8722086
157 + 8721929 = 8722086

Showing the first eight; more decompositions exist.
