Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2972, here are decompositions:
- 3 + 2969 = 2972
- 19 + 2953 = 2972
- 139 + 2833 = 2972
- 181 + 2791 = 2972
- 223 + 2749 = 2972
- 241 + 2731 = 2972
- 283 + 2689 = 2972
- 313 + 2659 = 2972
Showing the first eight; more decompositions exist.
