Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8686340, here are decompositions:

31 + 8686309 = 8686340
43 + 8686297 = 8686340
67 + 8686273 = 8686340
127 + 8686213 = 8686340
151 + 8686189 = 8686340
163 + 8686177 = 8686340
181 + 8686159 = 8686340
193 + 8686147 = 8686340

Showing the first eight; more decompositions exist.
