Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719018, here are decompositions:

101 + 8718917 = 8719018
131 + 8718887 = 8719018
137 + 8718881 = 8719018
149 + 8718869 = 8719018
167 + 8718851 = 8719018
179 + 8718839 = 8719018
239 + 8718779 = 8719018
281 + 8718737 = 8719018

Showing the first eight; more decompositions exist.
