Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86918, here are decompositions:
- 61 + 86857 = 86918
- 67 + 86851 = 86918
- 151 + 86767 = 86918
- 199 + 86719 = 86918
- 229 + 86689 = 86918
- 241 + 86677 = 86918
- 331 + 86587 = 86918
- 379 + 86539 = 86918
Showing the first eight; more decompositions exist.
