Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40864, here are decompositions:
- 11 + 40853 = 40864
- 17 + 40847 = 40864
- 23 + 40841 = 40864
- 41 + 40823 = 40864
- 101 + 40763 = 40864
- 113 + 40751 = 40864
- 167 + 40697 = 40864
- 227 + 40637 = 40864
Showing the first eight; more decompositions exist.
