Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40862, here are decompositions:
- 13 + 40849 = 40862
- 43 + 40819 = 40862
- 61 + 40801 = 40862
- 103 + 40759 = 40862
- 163 + 40699 = 40862
- 223 + 40639 = 40862
- 271 + 40591 = 40862
- 331 + 40531 = 40862
Showing the first eight; more decompositions exist.
