Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40980, here are decompositions:
- 7 + 40973 = 40980
- 19 + 40961 = 40980
- 31 + 40949 = 40980
- 41 + 40939 = 40980
- 47 + 40933 = 40980
- 53 + 40927 = 40980
- 83 + 40897 = 40980
- 97 + 40883 = 40980
Showing the first eight; more decompositions exist.
