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.
