Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123868, here are decompositions:
- 5 + 123863 = 123868
- 47 + 123821 = 123868
- 131 + 123737 = 123868
- 137 + 123731 = 123868
- 149 + 123719 = 123868
- 167 + 123701 = 123868
- 191 + 123677 = 123868
- 317 + 123551 = 123868
Showing the first eight; more decompositions exist.
