Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8713818, here are decompositions:

5 + 8713813 = 8713818
7 + 8713811 = 8713818
11 + 8713807 = 8713818
37 + 8713781 = 8713818
97 + 8713721 = 8713818
109 + 8713709 = 8713818
227 + 8713591 = 8713818
241 + 8713577 = 8713818

Showing the first eight; more decompositions exist.
