Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16312, here are decompositions:
- 11 + 16301 = 16312
- 59 + 16253 = 16312
- 83 + 16229 = 16312
- 89 + 16223 = 16312
- 173 + 16139 = 16312
- 239 + 16073 = 16312
- 251 + 16061 = 16312
- 311 + 16001 = 16312
Showing the first eight; more decompositions exist.
