Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701386, here are decompositions:

19 + 8701367 = 8701386
37 + 8701349 = 8701386
97 + 8701289 = 8701386
107 + 8701279 = 8701386
179 + 8701207 = 8701386
193 + 8701193 = 8701386
223 + 8701163 = 8701386
263 + 8701123 = 8701386

Showing the first eight; more decompositions exist.
