Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40704, here are decompositions:
- 5 + 40699 = 40704
- 7 + 40697 = 40704
- 11 + 40693 = 40704
- 67 + 40637 = 40704
- 107 + 40597 = 40704
- 113 + 40591 = 40704
- 127 + 40577 = 40704
- 173 + 40531 = 40704
Showing the first eight; more decompositions exist.
