Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86280, here are decompositions:

11 + 86269 = 86280
17 + 86263 = 86280
23 + 86257 = 86280
31 + 86249 = 86280
37 + 86243 = 86280
41 + 86239 = 86280
71 + 86209 = 86280
79 + 86201 = 86280

Showing the first eight; more decompositions exist.
