Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40904, here are decompositions:
- 7 + 40897 = 40904
- 37 + 40867 = 40904
- 103 + 40801 = 40904
- 211 + 40693 = 40904
- 277 + 40627 = 40904
- 307 + 40597 = 40904
- 313 + 40591 = 40904
- 373 + 40531 = 40904
Showing the first eight; more decompositions exist.
