Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39406, here are decompositions:
- 23 + 39383 = 39406
- 47 + 39359 = 39406
- 83 + 39323 = 39406
- 89 + 39317 = 39406
- 113 + 39293 = 39406
- 167 + 39239 = 39406
- 173 + 39233 = 39406
- 179 + 39227 = 39406
Showing the first eight; more decompositions exist.
