Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91388, here are decompositions:
- 7 + 91381 = 91388
- 19 + 91369 = 91388
- 79 + 91309 = 91388
- 97 + 91291 = 91388
- 139 + 91249 = 91388
- 151 + 91237 = 91388
- 229 + 91159 = 91388
- 307 + 91081 = 91388
Showing the first eight; more decompositions exist.
