Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718906, here are decompositions:

19 + 8718887 = 8718906
29 + 8718877 = 8718906
37 + 8718869 = 8718906
47 + 8718859 = 8718906
67 + 8718839 = 8718906
73 + 8718833 = 8718906
83 + 8718823 = 8718906
103 + 8718803 = 8718906

Showing the first eight; more decompositions exist.
