Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40906, here are decompositions:
- 3 + 40903 = 40906
- 23 + 40883 = 40906
- 53 + 40853 = 40906
- 59 + 40847 = 40906
- 83 + 40823 = 40906
- 167 + 40739 = 40906
- 197 + 40709 = 40906
- 269 + 40637 = 40906
Showing the first eight; more decompositions exist.
