Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8686398, here are decompositions:

29 + 8686369 = 8686398
37 + 8686361 = 8686398
89 + 8686309 = 8686398
101 + 8686297 = 8686398
107 + 8686291 = 8686398
139 + 8686259 = 8686398
157 + 8686241 = 8686398
191 + 8686207 = 8686398

Showing the first eight; more decompositions exist.
