Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86404, here are decompositions:

5 + 86399 = 86404
23 + 86381 = 86404
47 + 86357 = 86404
53 + 86351 = 86404
107 + 86297 = 86404
113 + 86291 = 86404
233 + 86171 = 86404
293 + 86111 = 86404

Showing the first eight; more decompositions exist.
