Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701866, here are decompositions:

13 + 8701853 = 8701866
53 + 8701813 = 8701866
109 + 8701757 = 8701866
137 + 8701729 = 8701866
157 + 8701709 = 8701866
163 + 8701703 = 8701866
223 + 8701643 = 8701866
307 + 8701559 = 8701866

Showing the first eight; more decompositions exist.
