Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40994, here are decompositions:
- 61 + 40933 = 40994
- 67 + 40927 = 40994
- 97 + 40897 = 40994
- 127 + 40867 = 40994
- 181 + 40813 = 40994
- 193 + 40801 = 40994
- 223 + 40771 = 40994
- 367 + 40627 = 40994
Showing the first eight; more decompositions exist.
