Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40772, here are decompositions:
- 13 + 40759 = 40772
- 73 + 40699 = 40772
- 79 + 40693 = 40772
- 163 + 40609 = 40772
- 181 + 40591 = 40772
- 229 + 40543 = 40772
- 241 + 40531 = 40772
- 313 + 40459 = 40772
Showing the first eight; more decompositions exist.
