Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722986, here are decompositions:

5 + 8722981 = 8722986
17 + 8722969 = 8722986
37 + 8722949 = 8722986
73 + 8722913 = 8722986
109 + 8722877 = 8722986
127 + 8722859 = 8722986
157 + 8722829 = 8722986
197 + 8722789 = 8722986

Showing the first eight; more decompositions exist.
