Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91188, here are decompositions:
- 5 + 91183 = 91188
- 29 + 91159 = 91188
- 37 + 91151 = 91188
- 47 + 91141 = 91188
- 59 + 91129 = 91188
- 61 + 91127 = 91188
- 67 + 91121 = 91188
- 89 + 91099 = 91188
Showing the first eight; more decompositions exist.
