Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71112, here are decompositions:
- 23 + 71089 = 71112
- 31 + 71081 = 71112
- 43 + 71069 = 71112
- 53 + 71059 = 71112
- 73 + 71039 = 71112
- 89 + 71023 = 71112
- 101 + 71011 = 71112
- 113 + 70999 = 71112
Showing the first eight; more decompositions exist.
