Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43142, here are decompositions:
- 79 + 43063 = 43142
- 139 + 43003 = 43142
- 163 + 42979 = 43142
- 181 + 42961 = 43142
- 199 + 42943 = 43142
- 241 + 42901 = 43142
- 283 + 42859 = 43142
- 313 + 42829 = 43142
Showing the first eight; more decompositions exist.
