Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12318, here are decompositions:

17 + 12301 = 12318
29 + 12289 = 12318
37 + 12281 = 12318
41 + 12277 = 12318
67 + 12251 = 12318
79 + 12239 = 12318
107 + 12211 = 12318
157 + 12161 = 12318

Showing the first eight; more decompositions exist.
