Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86864, here are decompositions:
- 3 + 86861 = 86864
- 7 + 86857 = 86864
- 13 + 86851 = 86864
- 97 + 86767 = 86864
- 277 + 86587 = 86864
- 331 + 86533 = 86864
- 373 + 86491 = 86864
- 397 + 86467 = 86864
Showing the first eight; more decompositions exist.
