Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8686218, here are decompositions:

5 + 8686213 = 8686218
11 + 8686207 = 8686218
29 + 8686189 = 8686218
31 + 8686187 = 8686218
41 + 8686177 = 8686218
59 + 8686159 = 8686218
71 + 8686147 = 8686218
97 + 8686121 = 8686218

Showing the first eight; more decompositions exist.
