Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12338, here are decompositions:
- 37 + 12301 = 12338
- 61 + 12277 = 12338
- 97 + 12241 = 12338
- 127 + 12211 = 12338
- 181 + 12157 = 12338
- 229 + 12109 = 12338
- 241 + 12097 = 12338
- 331 + 12007 = 12338
Showing the first eight; more decompositions exist.
