Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16406, here are decompositions:
- 37 + 16369 = 16406
- 43 + 16363 = 16406
- 67 + 16339 = 16406
- 73 + 16333 = 16406
- 139 + 16267 = 16406
- 157 + 16249 = 16406
- 223 + 16183 = 16406
- 337 + 16069 = 16406
Showing the first eight; more decompositions exist.
