Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91140, here are decompositions:
- 11 + 91129 = 91140
- 13 + 91127 = 91140
- 19 + 91121 = 91140
- 41 + 91099 = 91140
- 43 + 91097 = 91140
- 59 + 91081 = 91140
- 61 + 91079 = 91140
- 107 + 91033 = 91140
Showing the first eight; more decompositions exist.
