Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722134, here are decompositions:

11 + 8722123 = 8722134
17 + 8722117 = 8722134
37 + 8722097 = 8722134
41 + 8722093 = 8722134
53 + 8722081 = 8722134
101 + 8722033 = 8722134
107 + 8722027 = 8722134
137 + 8721997 = 8722134

Showing the first eight; more decompositions exist.
