Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91568, here are decompositions:
- 109 + 91459 = 91568
- 157 + 91411 = 91568
- 181 + 91387 = 91568
- 199 + 91369 = 91568
- 271 + 91297 = 91568
- 277 + 91291 = 91568
- 331 + 91237 = 91568
- 409 + 91159 = 91568
Showing the first eight; more decompositions exist.
