Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91208, here are decompositions:
- 67 + 91141 = 91208
- 79 + 91129 = 91208
- 109 + 91099 = 91208
- 127 + 91081 = 91208
- 199 + 91009 = 91208
- 211 + 90997 = 91208
- 277 + 90931 = 91208
- 307 + 90901 = 91208
Showing the first eight; more decompositions exist.
