Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40786, here are decompositions:
- 23 + 40763 = 40786
- 47 + 40739 = 40786
- 89 + 40697 = 40786
- 149 + 40637 = 40786
- 227 + 40559 = 40786
- 257 + 40529 = 40786
- 293 + 40493 = 40786
- 353 + 40433 = 40786
Showing the first eight; more decompositions exist.
