Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80940, here are decompositions:
- 7 + 80933 = 80940
- 11 + 80929 = 80940
- 17 + 80923 = 80940
- 23 + 80917 = 80940
- 29 + 80911 = 80940
- 31 + 80909 = 80940
- 43 + 80897 = 80940
- 107 + 80833 = 80940
Showing the first eight; more decompositions exist.
