Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43042, here are decompositions:
- 5 + 43037 = 43042
- 23 + 43019 = 43042
- 29 + 43013 = 43042
- 53 + 42989 = 43042
- 89 + 42953 = 43042
- 113 + 42929 = 43042
- 179 + 42863 = 43042
- 269 + 42773 = 43042
Showing the first eight; more decompositions exist.
