Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86388, here are decompositions:

7 + 86381 = 86388
17 + 86371 = 86388
19 + 86369 = 86388
31 + 86357 = 86388
37 + 86351 = 86388
47 + 86341 = 86388
97 + 86291 = 86388
101 + 86287 = 86388

Showing the first eight; more decompositions exist.
