Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12320, here are decompositions:

19 + 12301 = 12320
31 + 12289 = 12320
43 + 12277 = 12320
67 + 12253 = 12320
79 + 12241 = 12320
109 + 12211 = 12320
157 + 12163 = 12320
163 + 12157 = 12320

Showing the first eight; more decompositions exist.
