Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40938, here are decompositions:
- 5 + 40933 = 40938
- 11 + 40927 = 40938
- 41 + 40897 = 40938
- 59 + 40879 = 40938
- 71 + 40867 = 40938
- 89 + 40849 = 40938
- 97 + 40841 = 40938
- 109 + 40829 = 40938
Showing the first eight; more decompositions exist.
