Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722186, here are decompositions:

17 + 8722169 = 8722186
89 + 8722097 = 8722186
107 + 8722079 = 8722186
167 + 8722019 = 8722186
197 + 8721989 = 8722186
257 + 8721929 = 8722186
269 + 8721917 = 8722186
449 + 8721737 = 8722186

Showing the first eight; more decompositions exist.
