Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86398, here are decompositions:

17 + 86381 = 86398
29 + 86369 = 86398
41 + 86357 = 86398
47 + 86351 = 86398
101 + 86297 = 86398
107 + 86291 = 86398
149 + 86249 = 86398
197 + 86201 = 86398

Showing the first eight; more decompositions exist.
