Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8686372, here are decompositions:

3 + 8686369 = 8686372
11 + 8686361 = 8686372
59 + 8686313 = 8686372
113 + 8686259 = 8686372
131 + 8686241 = 8686372
179 + 8686193 = 8686372
251 + 8686121 = 8686372
269 + 8686103 = 8686372

Showing the first eight; more decompositions exist.
