Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718886, here are decompositions:

5 + 8718881 = 8718886
17 + 8718869 = 8718886
47 + 8718839 = 8718886
53 + 8718833 = 8718886
83 + 8718803 = 8718886
89 + 8718797 = 8718886
107 + 8718779 = 8718886
149 + 8718737 = 8718886

Showing the first eight; more decompositions exist.
