Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86380, here are decompositions:

11 + 86369 = 86380
23 + 86357 = 86380
29 + 86351 = 86380
83 + 86297 = 86380
89 + 86291 = 86380
131 + 86249 = 86380
137 + 86243 = 86380
179 + 86201 = 86380

Showing the first eight; more decompositions exist.
