Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86436, here are decompositions:

13 + 86423 = 86436
23 + 86413 = 86436
37 + 86399 = 86436
47 + 86389 = 86436
67 + 86369 = 86436
79 + 86357 = 86436
83 + 86353 = 86436
113 + 86323 = 86436

Showing the first eight; more decompositions exist.
