Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12308, here are decompositions:
- 7 + 12301 = 12308
- 19 + 12289 = 12308
- 31 + 12277 = 12308
- 67 + 12241 = 12308
- 97 + 12211 = 12308
- 151 + 12157 = 12308
- 199 + 12109 = 12308
- 211 + 12097 = 12308
Showing the first eight; more decompositions exist.
