Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719818, here are decompositions:

5 + 8719813 = 8719818
17 + 8719801 = 8719818
47 + 8719771 = 8719818
71 + 8719747 = 8719818
137 + 8719681 = 8719818
157 + 8719661 = 8719818
227 + 8719591 = 8719818
241 + 8719577 = 8719818

Showing the first eight; more decompositions exist.
