Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16486, here are decompositions:
- 5 + 16481 = 16486
- 53 + 16433 = 16486
- 59 + 16427 = 16486
- 137 + 16349 = 16486
- 167 + 16319 = 16486
- 233 + 16253 = 16486
- 257 + 16229 = 16486
- 263 + 16223 = 16486
Showing the first eight; more decompositions exist.
