Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40768, here are decompositions:
- 5 + 40763 = 40768
- 17 + 40751 = 40768
- 29 + 40739 = 40768
- 59 + 40709 = 40768
- 71 + 40697 = 40768
- 131 + 40637 = 40768
- 191 + 40577 = 40768
- 239 + 40529 = 40768
Showing the first eight; more decompositions exist.
