Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86412, here are decompositions:

13 + 86399 = 86412
23 + 86389 = 86412
31 + 86381 = 86412
41 + 86371 = 86412
43 + 86369 = 86412
59 + 86353 = 86412
61 + 86351 = 86412
71 + 86341 = 86412

Showing the first eight; more decompositions exist.
