Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115386, here are decompositions:

23 + 115363 = 115386
43 + 115343 = 115386
59 + 115327 = 115386
67 + 115319 = 115386
83 + 115303 = 115386
107 + 115279 = 115386
127 + 115259 = 115386
137 + 115249 = 115386

Showing the first eight; more decompositions exist.
