Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115666, here are decompositions:
- 3 + 115663 = 115666
- 29 + 115637 = 115666
- 53 + 115613 = 115666
- 113 + 115553 = 115666
- 167 + 115499 = 115666
- 197 + 115469 = 115666
- 347 + 115319 = 115666
- 443 + 115223 = 115666
Showing the first eight; more decompositions exist.
