Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40928, here are decompositions:
- 31 + 40897 = 40928
- 61 + 40867 = 40928
- 79 + 40849 = 40928
- 109 + 40819 = 40928
- 127 + 40801 = 40928
- 157 + 40771 = 40928
- 229 + 40699 = 40928
- 331 + 40597 = 40928
Showing the first eight; more decompositions exist.
