Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40986, here are decompositions:
- 13 + 40973 = 40986
- 37 + 40949 = 40986
- 47 + 40939 = 40986
- 53 + 40933 = 40986
- 59 + 40927 = 40986
- 83 + 40903 = 40986
- 89 + 40897 = 40986
- 103 + 40883 = 40986
Showing the first eight; more decompositions exist.
