Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86320, here are decompositions:

23 + 86297 = 86320
29 + 86291 = 86320
71 + 86249 = 86320
137 + 86183 = 86320
149 + 86171 = 86320
251 + 86069 = 86320
293 + 86027 = 86320
389 + 85931 = 86320

Showing the first eight; more decompositions exist.
